Amazon offers Amazon Prime members the Rubbermaid 23" Foldable Canvas Laundry Hamper, model no. 4D06, for $13.94 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $20.92.) That's the lowest total price we could find, outside of the price below, by $5. (We also saw it for slightly less in December.) Sales tax is added where applicable. It's stain-resistant and collapsible.

A close price: Walmart sells it for $11.47 plus $3.97 for shipping, however sales tax is added in more locations. (Free Site-to-Store pickup is also available.)

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months. (Note that there is no longer a waiting list for Amazon Mom.)
