June 2026 Extra Credit PetSmart $15 gift card doesn't provide Add to Cart button

 I completed the associated activities, but when I click to purchase this $15 PetSmart gift card for $12, it opens but there is no add to cart link to click. I've tried all the other gift cards for this activity & they all offer the CART link for purchase properly.  I'm wondering if it could be because I purchased, with points, the $5 PetSmart gift card in one of the other groups of activities for June, though I'm not getting any kind of message stating I don't qualify to make the purchase. Please advise.
