I think the system did not recognize the coupon,
No matter if you redeem you get the product bonus points...
Last time I will say 2 weeks ago,I had offer get 20x points when you buy enfamil formula.
I bought 2 packs for almost $80 used $20 coupon,redeem $60(38000points).
Paid $0.67 from my pocket and got almost 16700 points($20 value)...
I mostly redeem on smaller level but use the product points coupons to get back my points...
So if you see I redeem 38000 points for $60 but I got 16500 points back which means I only redeem 22000 points for $60....but originally $22000 points=$30
