Does anyone patch inner tubes anymore? Many years ago I bought a 100 pack of REMA round patches from Amazon.  And back then you could buy patch kits for $1 that had a few patches, something abrasive to sand with, and a tiny tube of vulcanizing glue.
It wasn't a good idea (in my experience) to buy anything bigger than a tiny tube of vulcanizing glue (unless you patch many tubes at a time) since the whole thing usually dried up after being exposed to air.
So nowadays you can't find those patch kits as cheap as $1 anymore and I'm noticing that places like Wal-Mart can sell inner tubes for as cheap as less than $5.
So unless anyone knows a good source of where to buy those tiny tubes of vulcanizing glue, I'm thinking it's just more cost-effective (and trouble-free) to just go w/ new inner tubes instead of patching.
What do you guys think?
Yes, some people still patch their tubes
I've worked sales at a bike shop for three years, and patch kits are still one of the most common small items for us to sell. It still makes sense from an money perspective--a patch kit is $2 and can fix 10 tubes, while tubes are $10 dollars each (for good ones, at least).
