I'm suffering from a bad case of it.
I bought myself a KitchenAide Mixer. I've wanted one for ages.
I stalked all the stores for the best price. I had a choice of a $50 GC to a store of my choice thru by bank rewards. So it was like $50 coupon.
The best deal I thought was Bath, Bath and Beyond. All said and done I got the Artisan Mixer for $250 OOP.
I still want the mixer. But I'm tempted to buy the Classic for only $199. I'd save myself $150.
*decisions*decisions*

So, again, go with what you wanted. Buyers remorse stinks, but I find it even worse when you realize you settled for something lesser because you wanted to save the money... and if you bought what you originally wanted you'd be fine. I happened to get online and see a good deal for the one I want yesterday, so I bought it! I'll sell my other one to help make up the cost
