I don't think there are coupon codes for PA ~
I order my juices from them, anyway.
An fyi to anyone interested:
Some general e-cig suppliers sell diy flavors listed as "TPA", "LorAnn's", "Flavour Arts", etc.
The cost may be a bit less (or they have coupon codes, etc), but it may not be worth it in the long run, imho.
I went this route once, while ordering some clearo's etc. I trusted this company and had used them many times for other products.
Unfortunately, the "TPA" flavor was not up to standard. It may have been diluted with PG or perhaps it had been on the shelf too long. Whatever the reason, it didn't blend well and I wasted a good bit of Nic base in the long run.
Since then, I go directly to the source.
