(whispering....) I always try almond or 2 when I buy those "in bulk" (to make sure they are actually -roasted-). Is it considered as "cheap"?
My former (thankfully!) co-worker (guy with the very good salary) was buying electronics (and not only) with the rebate coupons, sent coupons in, and then returned the items (he did it on regular basis and was very proud of his "extra-income").
I also know that some people buy nice dress, keep all tags on, use it once to go to wedding and such, and then return it back in store as "new". Now that is gross IMHO.
