Never took advantage of a 4/20 sale before, thinkin about picking up a Da Buddha vape, who can find the best price!
I got my DBV on eBay for $130. I've never seen any 420 sales for the DBV but if you watch eBay you can get a good price but probably not the warranty.
I got mine for $150 on Amazon which didn't come with the warranty, haven't had any issues with it. It's only like $30 at most to fix the worst problem, and they will take it in regardless of a presence of a warranty or not.
