I have a new in package Tupperware Stuffables Container. 4-cup size. I over-ordered and so it sits... (I'm not a Tupperware lady, BTW). Retails for $12 plus shipping. You can have this one for $5 plus actual shipping.
Box weighs 1 pound 2 ounces. My zip code is 92020. Priority will cost you $3.95-$5.75 depending on your zone. Parcel post will cost you roughly $3-$4.50 depending on where you live. Free DC included in price.
