Yeah, the e-mails are very confusing as to what you can use them for. They forever use specific examples, but in most cases it's for anything on the website except for gift cards. When they have drugstore.com on it also includes their gift cards, and today was an all gift card day on their corporate perks site.

It's probably the number one question people have asked in the different forums about it, do you have to buy what they use as the example.

My suggestions -

If you use twitter, make them a friend so you get the daily notices, they come out before the e-mails do usually

If you have not done so, get into the practice area and practice where the buttons are you need to click, where the text entry is, etc. You only have four or five seconds on the popular ones, so you need to know where you have to click when the screen changes, moving your mouse takes too long

I maximize my rewards by trying to buy as close to the minimum as possible. If it's a $50 rebate on a $100 minimum at Toys R Us (they had 4,000 of them two weeks ago, I think everybody won that one), I'll try to spend a few pennies over $100 so it's a 50% savings. There's no additional benefit for spending $300 at that time.

Remember too applying any other discounts, coupons, Gift codes, etc will usually void your credit back, so pay the $9 shipping instead of using the free shipping coupon to get the credit.

After you try each time, check your reservations it will give you how long they were available, how long it took you, and how many you missed it by.

It will help you figure out which ones are worth your time or not, the really popular ones (Starbucks, Home Depot) are pretty impossible to get.

I've saved hundreds of dollars on stuff since I started using it in August.
