UPDATE: You can snag even more Tetra coupons on the Tetra Facebook page under the Coupons for Fans tab (thanks, Kathy!)
If you missed this rare $2/1 Tetra coupon, it’s back again (I’m not sure that it’s reset though?!). Just head on over to coupons.com to print it (use zip 35803) and then check out the deal you can score at Walmart:
Tetra Tank Nibblers (18 tablets) $1.62
Use the $2/1 coupon found here
Final cost – better than FREE!
