I just had a weird experience with the Shop with Chase Portal. I bought a phone through the Best Buy offer (1%), the total was $1019 after tax. So I used gift cards bought via Chase Pay at Best Buy to get that 5% back. $1000 with gift cards and $19 with my CFU.
I got 950 UR pts from this purchase. I thought this alone was funny, because I only used my CFU for just $19 of the $1019. The phone is 950 before tax.
A week later, they drop the price of the phone and they reimbursed me for $200 for the difference. So my $19 that I paid through my CFU got "returned" and I got some credit on my gift cards.
My CFU statement posted yesterday and I still got 950 UR pts from the Best Buy purchase. I thought the offer would be invalid if you "returned" the product. On my statement, it looks like the best buy transaction got reversed. Oh well, I'll take 950 UR pts.
