PowerTri.com is a partner of the DC Tri Club, offering a discount to club members. But now they are holding a general liquidation sale, 50% off everything. The product selection is not that great but it could be worth a look if you need to buy some tri gear.
It's unclear what their long-term plans are, whether or not they will reopen the online store at some point after they sell all their current merchandise.
A lot of the items don't show up on sale when you try to buy them. Might be some problems with the site still.
