This Wednesday lighting deal expired…
The Canon 17-40mm f/4L EF Ultra Wide Angle is a lightning deal at Amazon going for $674 with free shipping until Thursday at 2:04am ET (or earlier if sold out). The price before the sale was $749 last night when I posted the lightning deals schedule. So this is a 10% discount on last night’s price. Non-Prime members can purchase this starting at 8:34pm ET tonight.
