If this had been a gift for a family or friend, I'd fight it...but since I was just going to give it away anyway, it's not worth the fight. I might call tomorrow, but it's just going to make my blood boil even more.
What is the most frustrating is thinking about all of the other deals, coupons, price breaks and other discounts I (think I have) gotten on Amazon. I'm now wondering how many of my orders had a bait and switch like this.
In this case, the evidence of funny business is clear as day (see attached). I didn't even buy the lego cupcake thing the first time it became available at this price. The first time, I was on the fence and by the time I clicked through, it was dead. The second time, I didn't bother changing the quantity to 2 because I didn't want to lose it again...so I bought only one. But it's not like the coupon was a mistake...it came, went, and came again.
I also bought Minecraft lego set for like $4.40 (which actually is for a nephew) and that seems to have been charged correctly.
