For those in the Houston Area,
Alvin E-cigs is at Trader's Village on the weekends. You can try out different PV's, parts & a few flavors, but any flavor you want if you call him ahead of time-he'll bring it.

I haven't dealt with them personally yet, but they carry a good selection of good products with great prices.
