So far I've tried mt baker vapor, copper creek and nicoticket.
MBV- great prices, fast shipping, some great juices. Great variety. Lately flavors have been OOS due to supplier issues but that should resolve itself soon. Try sticky bun, graham cracker, caramel candy.
CC- convenience somewhat less (only open during business hours) fewer but higher quality juice selection. Usually ships in 48 hours or less. Nothing new here but I like house blend a lot. Ships to my house pretty quickly. Prices are average to high but not 5 pawns high.
Nicoticket- relatively new vendor, still limited but well vetted selection. The 4 juices I've tried have all been great. Order with patience, one man and one child show. If you order the pre steeped CLS or CB in 6/12/18mg it ships in 48hours or less. 50/50 on CLS or 65/35 for the CB (might be wrong on the exact numbers) can't go wrong with anything he offers.
