Walmart offers the True Lime 100-Count Sachet Box for $7.88 with free shipping. (Amazon charges the same with free shipping for Prime members.) That's tied with our mention from a month ago and the lowest price we could find by $4. These sachets replace lime wedges in drinking water and tea or while cooking.

Update: It's now out of stock at Walmart; however, Amazon still offers it for $7.88 with free shipping for Prime members.
