Where to Buy: Every Retailer, Every Price, in One View

Pick any product you sell, say a laptop, and ask a simple question: what is it selling for right now across every retailer that stocks it? Most brands cannot answer that without opening eight browser tabs and writing prices into a spreadsheet by hand. By the time they finish, the prices have already moved. The Where-to-Buy view in Crawlbot answers it in one screen: every UK retailer carrying the product, with live price, stock status, and who is currently cheapest, side by side.

That sounds like a convenience feature. It is actually the cleanest way to spot a problem you would otherwise never see: the same product, on the same day, selling for meaningfully different prices depending on where a shopper lands.

A GBP50 spread on the same day

Here is a real shape of the problem. Take the Acer Swift Go 14. On a single day we tracked it across five UK retailers, and the price ranged from GBP849 to GBP899:

Retailer	Price	Stock	Position
Amazon UK	GBP849	In stock	Cheapest
Very	GBP879	In stock	+GBP30
AO	GBP889	In stock	+GBP40
Currys	GBP899	In stock	+GBP50
Argos	GBP899	In stock	+GBP50

A GBP50 gap on the same SKU, same day. A shopper who runs a quick comparison search sees all five at once and almost always clicks the cheapest. The brand, meanwhile, sees none of this unless someone goes looking. That asymmetry is the whole point: the shopper has the full picture and the brand does not.

None of these prices is wrong on its own. The problem is the spread, and what it quietly does to the brand.

Why the spread matters

A price gap across retailers is rarely just noise. It usually points at one of a few things worth acting on:

• MAP and RRP compliance. If you set a minimum advertised price or an RRP, a retailer sitting well under it is breaking the agreement. You cannot enforce a floor you cannot see. A side-by-side view makes a breach obvious the hour it happens, not at the end of the month.
• Channel conflict. When one retailer undercuts the rest by GBP50, the others notice. They either match it, which drags your whole shelf down, or they quietly push your product lower in their rankings in favour of a brand that holds price better. Either way you lose.
• Lost sales from stock and mispricing. The cheapest retailer goes out of stock and nobody tells you. Now the shelf shoppers see starts at GBP30 higher, and some of them walk. Or a retailer fat-fingers a price the wrong way and you are suddenly the expensive option in every comparison engine.

The Swift Go example is mild: everyone in stock, a clean GBP50 band, no obvious breach. But the same view is where the ugly cases show up first, the retailer GBP120 under RRP, the one that has been out of stock for a week, the comparison-engine listing pulling from a stale feed. You are watching the same screen either way.

This is the day-to-day side of price monitoring across UK retailers, turned into something you can actually look at instead of a wall of rows. And because a price can change many times in a single month, a one-off manual check is close to useless. By the time you have collected it, it is history.

What the view tracks, and how fresh it is

For any product, the Where-to-Buy view pulls four things per retailer and keeps them current:

• Retailer, every UK seller carrying that exact product, matched on MPN and EAN so you are comparing the same SKU, not a lookalike.
• Live price, what the retailer is showing a shopper right now, including any on-page promotional price rather than a stale catalogue figure.
• Stock status, in stock or out, so you can tell whether the cheapest option is one a shopper can actually buy today.
• Who is cheapest, the view ranks the retailers and flags the lowest live price, plus the gap to it.

It refreshes hourly. That cadence matters because retailer prices on consumer electronics move through the day, not once a week. An hourly view means that when a retailer drops under your floor at 11am, you know by noon, not at next month's review. The same engine sits behind tracking competitor prices across UK retailers, the difference here is the lens: one product across all its sellers, rather than one retailer across all its products.

Crawlbot runs this across the consumer-electronics digital shelf hourly in the UK, Poland, South Africa and the Nordics, roughly 7.4 million listings a month across 34 retailers. The Where-to-Buy view is simply that firehose narrowed to one product and pointed at the question a category manager actually asks.

What a brand team does with it

The view earns its place because it turns into action quickly:

• Catch breaches the day they happen. Sort by price, spot anyone under your RRP or MAP floor, and have the screenshot and timestamp ready before you pick up the phone to the account.
• Protect the shelf during a stockout. When your cheapest retailer sells out, you know the effective entry price just jumped, and you can lean on the next retailer to hold position or fix a feed before sales slip.
• Settle channel arguments with data. When a retailer complains they are being undercut, you are not guessing. You can show exactly who is GBP50 lower and whether it is a sanctioned promotion or a rogue listing.
• Keep your own pricing honest. If your RRP no longer matches where the market actually clears, the spread tells you that too, before the whole category drifts under you.

The core idea is small but it changes behaviour: shoppers already compare every retailer in one glance, so brands should be able to as well. When you see the same five prices the shopper sees, on the same screen, the GBP50 gaps stop being invisible and start being decisions.
