“In stock” doesn't mean what you think
Stock information is the least reliable thing on a product page, and the only part of the buying decision that is genuinely time-sensitive.
What the labels tend to mean
| What it says | What it often means |
|---|---|
| In stock | Available when the page was generated — which may be cached, sometimes for hours |
| Available to order | Not held. The shop will order it when you do. |
| Low stock — only 3 left | Sometimes true. Sometimes a fixed number shown to everyone. |
| Pre-order | Not released yet. Your card may still be charged. |
| Check store availability | Not held centrally. Depends entirely on your postcode. |
| Dispatched in 3–5 days | Usually honest, and usually better information than a stock label |
The pattern that costs people money
You find the cheapest shop, order, and a few days later get an email saying the item is delayed or cancelled. By then the second-cheapest shop has sold out or raised its price, and you buy at the third price. The headline saving was never available.
This is why an unusually cheap listing at an unfamiliar shop deserves a stock check before it deserves your card details.
Your rights if it doesn't arrive
If a retailer has not agreed a delivery date with you, it must deliver without undue delay — and within 30 days at the latest. If it misses that, you can set a new final deadline, and if that is missed too you are entitled to cancel and get a refund. A shop cannot simply hold your money indefinitely while it waits for stock.
Pre-orders deserve their own caution
A pre-order is a promise about a product that does not exist yet. Release dates slip, launch prices change, and early reviews sometimes arrive before your delivery does. Two practical points: check whether you are charged now or on dispatch, and remember that your right to cancel an online order still applies — a pre-order is not a binding commitment you cannot escape.
What to do when an order is cancelled on you
- Check whether you were charged. If so, the refund is due without undue delay — a retailer cannot hold your money for stock that does not exist.
- Do not assume the next-cheapest option is still available at the price you saw. Re-check before committing.
- If the shop cancelled because it mispriced the item, it is generally allowed to. A displayed price is an invitation to buy, not a binding offer, until the retailer accepts your order — which is usually at dispatch, not at payment.
What Arbi does about it
Where a shop states stock clearly on its page, Arbi shows it as “in stock when Arbi checked” — with the timing said out loud, because stock at the moment of checking is the only honest claim any tool can make. Where the page does not say, Arbi shows “stock: check” rather than assuming availability. Arbi cannot promise an item is there; nothing that reads a web page can.
