It's so nice to receive a package in the mail every day!
The fact is there are actually several sites that offer similar promotions. Some sites are nice to sign up for if you like to clip coupons. I usually clip coupons from the Sunday flyers in our newspaper. I don't want to have to use up our printer ink to print out coupons. For our printer at least, ink cartidges are very expensive. Although now there are some really nifty IPhone apps that allow you to have the cashier just scan the coupons off your phone. Neat! I haven't tried that yet, although I believe I do have an app for that.
It just takes a few minutes to fill out the forms for these samples. I hope the links are useful to others as they've been for me.
