do you use this? i don't like it! i pay for prime so i don't have to pay shipping and having to pay $5.99 to ship the box seems redundant (i already paid all my shipping for amazon for the year with my membership!). i know they were losing money on a lot of items, but i just tried to add something to my subscribe & save to ship tomorrow and they want to make me pay $5.99 shipping to have a 'prime pantry' box shipped or i can order it from a different seller & pay more than the amazon price.

has anyone found this prime pantry to be useful? am i missing something??
