Walmart offers a Customized Full-Photo 13-oz. Stainless Steel Tumbler in several styles (Color Collage pictured) for $10. Opt for in-store pickup to avoid the $2.75 shipping fee, or get free shipping with orders of $25 or more. That's $3 off and tied with our mention from two weeks ago as the lowest price we could find.
Laundry detergent is just as effective at removing spots as fancy stain removers — with one exception.
