That’s not right at all! Ask customer service what they think and post their response.
The most frustrating thing about S&S for me is that the prices fluctuate wildly from delivery to delivery. I have to waste so much time combing through my subscriptions every time a new one is about to ship, just to make sure I’m not paying extra that week.
Eventually, I ended up having to cancel it all after a few times when I couldn’t double-check and ended up paying more for a few items.
I found it better to simply set up a price alert, and buy non-urgent things when they are at a low price, stocking some extra if necessary.
