Check that the product, configuration and included items match. Different storage options, colors or bundles can have different prices even when their names look similar.
Use the history as context
Look at the available price history over more than one range. A recent low and a short-lived discount can tell different stories. Missing observations mean the available record may be incomplete.
Keep the final offer in view
A recorded price is a useful reference, but the seller controls the current offer. Confirm the price, availability and any delivery charges on the retailer’s website.
