I have mixed feelings about calling this one a tip.. but I've recently been interested in giving a shout out (think passive advertising) to open source technology I use and like (๐ง, ๐ฆ, vim, etc..).
I bought this set of 206 stickers from Amazon a few weeks ago for $10 (9.99, but that's really 10).
The stickers are very hard to peel off till you get the hang of it, but can vouch.
