{cvs.com - formula deal}

this is the second time i've taken advantage of this and gotten a great deal on formula from cvs.com...
every so often, they do 20% off the entire site for two days. it is currently going on for today (monday) and tomorrow. coupon code = sale20. there is also a deal if you spend $60, then you automatically get $10 off and free shipping. you can save an additional $5 by paying with a mastercard. the latter two deals do not require any type of promo code. though i've used this for formula, it could be equally beneficial to other items.

so, here is what my formula purchase looks like...
3 - 24oz cans of Enfamil Gentlease
Original Retail of $28.29 x 3 = $84.87
Less 20% = $67.90
Less $10 (order is above $60) = $57.90
Less $5 (paying w/ Mastercard) = $53. 58
total savings = $37.46
Price per ounce = 74 cents (significantly less than the cheapest retail prices I've found, which is at warehouse clubs)
