+1 vote for splitting Reptilinks orders with people.
This is probably the biggest problem I have with Reptilinks. The minimum order requirement makes them somewhat unviable for those of use with small groups, ie. pet keepers. I get the impression that the company may be waiting to more pet stores to start distributing their product to really break in to the pet-keeper side of the market. Which....meh.
How are you storing your links? If you keep them sealed and frozen, the unopened bags should be good for a year. Pairing the links with some fresh greens and veggies should help offset the loss of nutrients from aging.
