This is a nice set of Lock & Lock BPA-free tupperware (32 pc set) for $14.99 on Woot. Shipping is a flat $5 for 1-3 sets.
*UPDATE – if you buy 3 sets, use coupon code TAXSUCKS and you’ll get free shipping! (Thanks Sarah!)
If it works in the budget this would be a nice one to grab a few sets and save ahead for replacements for your own kitchen or use as Wedding gifts.
