I’m all bout the tee’s and hoodies. If they are nice people wear them and are proud of them. The best swag I have is always “wearable”. I still have/wear tee’s from various conferences, etc, going back 5+ years.
Flash drives look cool at first, but I don’t think many people use them any more. I have drawers full that never get used.
One of my fave pieces of swag is an old WordPress coffee mug I have, actually a set of 4 and I have been using them since 2008! People always ask me “where did you get that?”
I have a few really nice knapsacks too, hard to come by they ain’t cheap to make, but you could sell them to your uber fans or give them away in contest, promos, etc.
Stickers are always good - just saying!
Fitted baseball caps with an embroidered logo - so sweet!
I’ll second socks! I got a sweet pair from canux 2014 still love’em! They were made by Sucks By Williams a Canadian company.
Branded cables re cool, but too many different use cases and types of cables.
I also really dig posters. Cool art you can hang on your office wall. SXSW does a really good job of this every year. You could commission some local artist and do a series of “inspirational” Unbounce posters … “Collect them all!!”
I’m sure I can come up with more …
