I only needed one more item to “unlock extra savings up to 15%”, so I added an extra item to see what the savings would be. I didn’t think the savings matched what was advertised, so I removed an item to see what the difference was (making sure to screenshot before/after this time). Turns out the price of 3 out of 4 items is the same after an extra 5% discount.
I tried doing subscribe and save when they first introduced it, but it doesn’t lock in a price, and if it’s out of stock one month when it’s time to ship, it just cancels the whole thing even if it’s back in stock a week later. And the discount isn’t even that great. Frankly the whole program is shit imo and I’m amazed it’s still so shitty however many years later.
