Came across these guys while looking for a coupon for step ones. These guys are currently running a buy one get 2 free deal on purchases of 3.
If you combine it with "welcome 50" you get 6 pairs for $38.08 (around $6.35 each). Note for this to work you have to buy 2 X 3 packs. No longer working. Thanks Groook
I think the $0.08 fee is for PayPal.
This style of underwear is one I've found very comfortable. Hoping they honour the deal. Colours are limited from this company.
