⚠To check an offer, you can specifically for Amazon "Keepa" or "CamelCamelCamel" to use. Prices are tracked here, so you can see if an offer is really an offer.

Dealers like to use the tactic of adjusting a product from its normal price to a very expensive price, only to later sell it at that normal price (now much cheaper). With this tactic, the retailer triggers a price drop, which signals an offer for many online shops, websites, deal sites, price portals and positions it accordingly or makes it conspicuous. Use these tactics to your advantage and catch the periods before and after these price adjustments. This will certainly require a little time, planning and patience for your purchase.
