I'll give some examples of products/retailers; up&go, Lenovo, Grain Waves, Fratelli Fresh, eBay (more recently), Priceline, any work shirt, anything Xiaomi.
I know it's marketing and will attract new customers, but when they occur so often you can't bring yourself to pay full price so stop buying them altogether as the lower price is the price you 'expect' to pay.
Agree? Can you think of any other examples of stores/products?
Sometimes you need something immediately and don't have time to wait for a sale. In those cases, you'd have to pay full price and swallow your pride. Sometimes you have a lot of money and don't care if you squander some of it. No point in listing more stores or examples.
