I previously discussed a great deal on Similac Advance ready made formulas in my post here. The previous offer using promo codes got the cost down to $11.35 per shipped case; an excellent deal.
The current offer gets the price down to $10.09 shipped using promo codes LUTEIN and SIM3OFF.
Note, if you took advantage of the previous deal, using code LUTEIN, then you will not be able to take advantage of the same promotion if you use the same account; therefore, you may need to create a new account (email address) to order additional quantities. As I mentioned previously, you will only be able to add one (1) quantity to your cart to get the discount codes to work; in other words, if you try adding more than one to your cart, the discount will only discount one of the cases.
