Dear BettyKat,
I hope you read the T&C of the wishlist page. Incase not... here it is.
For Amazon, maximum savings amount not to exceed $125. This mean your max purchase will be $500. And it is only good for Amazon.com items, not any affiliates site.
For BB&B,
well in fact i had not read them (although i did know that it was good only for amazon.com items, but that includes quite a lot of brands). so good to know. i'm almost relieved - this makes it much easier for me.
as i said, the lizard brain was yelling to BUY! BUY! BUY!
