@mistercheap Yes the item (cell phone) is Shipped & Sold by Amazon, hence the $10/25 coming off. I added a phone case that is slightly above $25 and also Shipped & Sold by Amazon, and get the $10 discount even though the total is under $25. I see the option to Ship to Locker on the case (so free shipping), whereas it showed “Shipping” for the phone and the $5.99 charge.
The only thing I can think of is the phone is not allowed to be shipped to Locker, so if I pick Locker, it’s charging me to ship to Home. I suppose if would be the same if you pick a really large item that doesn’t fit in a Locker.
