I have never heard about
2TENTS4GROWING but if your seedshop in Massachusetts has recommended the breeder it will probably be ok. Mostly there are two problems to order/buy seeds on line or at a seedshop.
1. the seeds doesn't show up or
2. the seeds don't germinate
You can check out the following link:

The only thing which is a little bit surprised is the
TRUSTPILOT has
dropped 2TENTS4GROWING webpage and
https://www.2tents4growing.com/ DON'T say so much!
Good luck
