Based on recommendations from cruiser forums, blogs, and books the best solution for us is Tupperware. Continuous usage of an item requires it to be reliable and durable. Testimonials from the above mentioned references, all highly recommend Tupperware over any other brand of storage.
With the solution in hand, we started pricing new Tupperware and developed a case of sticker shock. New, just a couple of pieces can run upwards of $50. Based on our storage plan, we were going to need a lot, but we weren't willing to drop $500 or more on new Tupperware. We decided to try ebay.
While searching on ebay, I could not believe how many results came up for Tupperware, over 30,000. That's a lot of Tupperware! After looking at a lot of listings, we bid on a few and won a listing that had over 70 pieces of vintage(used) Tupperware for a total of $50.82 (included shipping).
The Tupperware was in great shape and I was amazed at how much each container could hold. We have filled and labeled all of the various pieces of Tupperware. They now reside on Ariel.
