I got pretty much all my equipment for fantastic deals...mostly because of the Bing Cashback that we had about 2.5 years back
Canon 40D (2.5 years back): 650$ after cashback
Canon 50 1.8 (2.5 years back): 75$ after cash back...I ended up giving this lens to a friend.
Canon 100mm Macro: (2.5 years back): 440$ after cashback. Best IQ of any lens I own.
Canon 24-70 (2.5 years back): 1120$ after cashback
Canon 10-22 (2.5 years back): 660$ after cashback...I just sold it 2 weeks back for 650$. The guy must be cusssing his luck after seeing the Amazon deal yesterday.
Canon 70-200 2.8 IS (1.5 years back and used): 1350$ after cashback on eBay. This is the only lens I got used....but it was in great condition and no problems so far.
Canon 580 EXII : 3 50$ after cashback.
Canon 5DMkII (2 months back): 2050$ from henrys in Canada...maybe I should have waited a month or so...but its ok.
Canon 16-35 (2 weeks back): for 1300 after Price Match from Adorama because of the Amazon deal yesterday.
A buddy of mine got a barely used 10-22 for 450$....some rich kid was bored of his gift...
I miss Bing Cashback.... But since its been gone, prices have risen (that and the yen/$ exchange rate), but if I sold all my equipment I could come out on top pretty easy i think.
