When USPS took an extra day to deliver and most of the slings died from heat (packing was great, it was very hot where I live), Seven Wonders overnighted replacements immediately. I would definitely recommend.
Pros - Healthy Tarantulas, well packed, fast shipping, great prices
I received 22 slings, and each one was packed perfectly. Only ordered 20, so 2 were freebies.
Also received two adult female pokies that were feisty upon arrival. If you are looking at their ad in the classifieds right now, jump on those prices and rest assured that your purchase will be perfect.
