Me: I got your promotional email last night and tried to use the coupon but it didn't go through on my phone. Can you apply the coupon now?
Store: Oh, oops, sorry. It's too late. It doesn't work on a phone, you have to use a desktop computer.
Me: You can't retroactively apply the coupon?
Store: Nope, the order's already gone through.
Me: But it was for 35% off which would save a lot - is there any way to help? I just ordered it last night.
Store: Nope, the order has advanced to another department now.
Me: Fine. Can I return it then? I'll just re-buy it from my computer so the coupon will work.
Store: Hmm... let me see what we can do...
(Magically, they were suddenly able to apply the discount...)
