I think if you have successfully pushed them through it should be ok. The issue was, two of my coupons somehow hadn't gone through the first time I tried to enter them, not long after purchase. One of them did go through, though, even though I thought all three had. I wouldn't have known had Groupon not written to me. There is always quite a long wait between redeeming the coupons/codes and actually receiving the Avios, so we could still have a bit of a wait in front of us. I have a feeling it will all work out.
