If you have a Unidays account, you can get a unique 25% off coupon code for logitech.com . That code is stackable with Logi5off which takes up to $10 off your purchase.
For example, I got an iPad Pro 12.9 keyboard case I've been keeping an eye on. $149.99 (same as other retailers) - 25% = $112.49 - $10 = $102.49, or nearly 33% off. (Aside from a firesale on the super purple model, I've never found a lower price on this).
PS: e b a t e s brings back 2%...
