I saw this deal in my email and on the ToysRUs/BabiesRUs board. Looks like a fairly good deal with coupons. There is also a promo for a $5 gift card when you buy any two Huggies Pure & Natural jumbo packs. Not sure if the $5 price is combinable with the gift card deal.
"Diaper Days Only$5 ea. ANY Fisher-Price jumbo pack (23-50 ct.), Babies”R”Us brand mega pack (40-66 ct.) and training pants, Seventh Generation jumbo pack (26-44 ct.), Earth’s Best jumbo pack (26-44 ct.) and training pants, Huggies Pure & Natural jumbo pack (20-33 ct.) and Huggies Little Movers Jeans jumbo pack (21-29 ct.) of diapers"
Has anyone ever tried the Babies R Us brand or Earth's Best training pants?
