I've avoided prime so far because $25 was low enough that I could easily bundle two or three items once a month and get the free shipping. The $35 limit now makes that a little harder since I usually buy items (e.g. toothpaste, soap) as bundled packs that last me a couple months at a time. So I just need one particular item, then I probably have to either wait until I have enough stuff to buy or make a trip to the store.
Honestly, it was fun while it lasted. Also note that if you are a student or still have an active edu account sitting around, you can get a up to four years of the discounted pricing at $39/yr, which makes it even more worth to get your items in 2 days rather than waiting two weeks.
