Too cool! My sister had a whole set of those scratch n sniff stickers. I can still recall the grape smell of that sticker. She stuck them everywhere.
The great thing about the gold rush of the Flashback series is that I have stacks and stacks of duplicates...and I use them. My wife and I have a small ebay business that sells vintage glass and pottery. EVERY package I ship out has a Wacky Pack sticker stuck to it. All those duplicates get put to good use. I have shipped Wackys all over the country, but I am always really excited when I get to ship them around the world. I don't know if other countries "get" the stickers or not, but I dig putting them out there. The folks at the post office are also always commenting on the "funny" stickers I put on the packages I ship. That's what makes life fun.
