Amazon offers the Persil ProClean Power-Caps Laundry Detergent 62-Pack in Original Scent for $13. Clip the $4 off coupon on the product page to cut that to $9. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $8.07.) That's $5 under last month's mention and $4 less than you'd pay at local stores. The pods function as a detergent, stain remover, and brightener.

Note, this item is currently on backorder but can still be purchased at this price.
