eBay is running a flash coupon sale: take $25 off purchases of $119+ with coupon code PRIMO119. The coupon should work on everything camera-related, so it’s handy if you are looking for something just above $120. The sale ends tonight at 11PM PT (2AM ET tomorrow).
Many authorized dealers do list items on eBay. For example, you can save $25 on the Canon EF 50mm f/1.8 STM at Adorama via eBay (authorized dealer), net $100!
