If you use similac then you will want to get in on this deal and FAST! Currently you can get 48 of the 2 oz bottles of similac advance, and 2 of the quart RTF for $25! Just go to Abbot Nutrition and order the 48 two oz bottles. It is $41.xx and it takes $50 to get free shipping. I added 2 of the 1 quart bottles of RTF at $5.99 each. This brought my total to $53.92. Use coupon code LUTEIN (expires 3.31.11) to take off $28.85! This brought my total down to $25.07 on the formula we use for Princess!!
