Lately, from PBK:
Campy Khamsin G3 wheel set, $117 w/skewers, $250 stateside. They had the Vento G3's for $177
Rear wheel bike stand $9, about 1/2 price
Conti tubes $5 and you know what LBS's are charging for decent tubes.
Shipping for all was $30, and no tax.
Another order, free shipping.
Descente tri-suit $33, generally 140-160 here. My wife says I need to lose weight to wear it.
Campy lock ring $13, couldn't find even a used one for $20 here
Michelin Speedium tires $12.50 ea, figure 1/2 price
Shimano HG-50 8-sp cassette $15, still less than here, especially shipped free.
Complete STI shifter/brake cable/housing sets $9 in grey. $30 here
They have the Mavic's on sale right now, and I think a local LBS is actually buying them and reselling 'em. He was mounting a set of Kysirium the other day, $850, and I think he bought them from PBK for $459.
You have to look around on their site, but they seem to always have some steals/deals.
You shouldn't change the Frisbee.
