During covid my boredom took over and I discovered how you can email tons of different brands, professional teams, schools, etc. saying that you're a big fan of them and want to support them by putting their stickers on your water bottle, laptop, etc. Lots of them got back to me and sent me stickers and a variety of other fun things. It was so exciting to go check the mail every day and get new envelopes with surprises. Anyways now I just continue collecting free stickers when I come across them but I have shoe boxes full of things I collected from that era
