in stores Enfamil tubs are about $24 each, i never pay more than $13 each but usually i can score them for about $10

and here’s how…
Target.

Target usually runs specials on Enfamil <buy 2 get $5 gift card or buy 3 get $10 gift card- right now it’s buy 2 get $10!> and on top of this you can use a Target coupon (which they’ll send you in the mail) + a manufacturer’s coupon + a rebate check (i’ve found Target employees don’t often look at the expiration date either, i feel like a flop for doing this but that’s $5 a tub folks, it’s not my fault they’re lazy)

even better - they also carry the refill boxes which are 2 bags for $34 and they offer the same GC deals so you can essentially get another one for $10 every time you buy.

if you’re a member, Sam’s Club has a decent deal on Enfamil too if you don’t have any coupons to use (because they don’t take coupons - so it’s a better deal at Target if you have some). they have 3 refill bag packs for $40 and you can use a rebate check on them.
