Walmart continues to offer the Duck Brand Shrink Film Indoor Window Kit 5-Pack, model no. 281504, for $7.47. (Amazon offers it for the same price with orders of $25 or more via its add-on program.) Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our mention from two weeks ago and the lowest price we could find by $8. It includes 62x210" of film.
