Sympathy Order - Some challenges experienced

Some initial challenges with platform, and the NF agent told me to clear my cart and my cache. I didn't do this, but went 'incognito' and solved that issue. The sympathy cards were totally out of stock, which you only find out when you checkout the cart - then you have to go back and remove them, plus try and find another one (the search function is not very intuitive). I think some system upgrades would be a good idea - so that you cannot select out-of-stock items and progress them to a cart. I also recommend QR code payment options for faster processing. I had to settle for a generic card - and I'm still not sure if the image on this card is/was appropriate (the image shown online was a gift box - not appropriate for a sympathy card). I completed the order, but it was a rather stressful story and I think there are a few opportunities to improve the customer experience here.
