New March 7% off code for eligible private sellers. I am sure it is similar to the previous monthly 7% off deals like this.
Q: How to find out eligible sellers/items?
A: Do a search on the item you want, the resulting listing should show the "eligible" ones with 7% off with coupon. Max $300 off alongside them.
Works on "eligible" private sellers, new or used items. Their T&Cs page is broken (what's new…) but I have found some sellers and tested it out. For example I searched sony a7, a few popped up.
