Well both behaviors occurred at the same time - the way it worked for you (and me) and the way like the website (no GC to pay if GC in the cart) - from what I recall so it's still not definitive I don't think. So it could be that's what the glitch is that somehow some stores got the website way, which isn't desirable, and that's what they're fixing. Or since some regions had already decided to not allow it due to fraud issues, it may be that they're trying programming options for those regions to opt into and the "glitch" was it was turned on nationwide. BUT, secretly I'm really thinking that this is the way it will work once they decide to change corporate policy; and they may be evaluating how much not allowing GC - GC purchases hurts the bottom line during this "glitch" period to then decide how/when/where to roll it out.
I'm trying to be optimistic about it even though it's not really in my nature
I hope your optimism works. I am not hopeful and will not be cashing out for Target gcs in the near future. After my trip, maybe since I often use target to send things to my son at college. But for now all my reward earnings are going towards a Disney trip so it's going to be mostly Paypal cash-outs for the next few months.
