Amazon offers a Tide Travel Sink Packet 3-Pack for 98 cents. Add it to your cart via Subscribe & Save to cut the price to 93 cents and bag free shipping. That's $2 under our mention from just over a year ago and the lowest total price we could find by $3. Each packet contains enough detergent to wash a few clothing items in a sink while traveling.

Be sure to cancel Subscribe & Save after your order arrives or you'll be billed for subsequent shipments.
