My local Target used to give me a hard time with using 2 coupons for the same item - so now I carry a copy of this when I go - it's their corporate policy to accept 2 coupons (one Target and one manufacturer).

EDIT: Just a general post - not specific to the Tag Jr - I know that has it's own issues!
Re: PSA: Target Coupons
I know that this isn't in reference to the Tag Jr post below, but I think the issue with using both coupons for the Tag Jr is the below exception in bold.
? Target accepts one manufacturer coupon and one Target coupon for the same item (unless prohibited)
The Tag coupon specifically says that you cannot combine it with any other offer and that they have a limit of one coupon per item purchased. The only reason I know this is because I did take in the policy and this is what I was told. I was hoping I would be able to smoke them over like everyone else.
