Not sure if the OP is planning to pre order provisions or shop in person. I prefer to shop in person (less chance of over buying and I like to pick my own produce). Riteway had better selection this time around.

Honestly, I just pick whichever store is closest to the base and go there. Buy basics, booze and 1-2 days of food and supplement as we go. This past week we were out of Hodges Creek. Landed in EIS, Taxi directly to RiteWay East End, taxi to base, off dock asap.
