Appears price isn't showing yet, but I believe the promotion should have started so may change throughout the day. Here is an image of promotion
I've got one (Polypro Unisex Long Sleeve Thermal Top v2 - Black) and would recommend quite easily @ $10, so if your looking for some thermals then have a look at these.
Doh! Just come back from Kathmandu. Would have purchased if realised it was available. Thanks though
