Looking for a deal on bigmos for canon

[jensgt]

I bought the sigma 150-500mm lens for 888 Sony mount last April....now I'm switching to a canon 7d so I'm looking to buy this lens again. It's 999 everywhere!!! Opteka.com has it for 899 with a coupon but I'm not sure if they are legit? Anybody know??

So if anybody knows any good coupon codes or specials going on at any good online stores let me know. Thanks guys.
