I could not combine orders / shipping for the same buyer. Followed normal procedure and option +

was no longer highlighted. I went to classic view, the my sold items, selected the two items, and at the top was combine shipping and it would not highlight to select. I ended up just shipping one item at the increased weight and put both items in the package and refunded the difference. I then thought I could just upload the tracking number to both (thought I have done this in the past) and it said tracking number is already in use. Very aggravating. I ended up uploading the tracking number on PayPal but who knows what that will do and hit "item shipped" on eBay for the second item. If my buyer is honest hopefully it will be fine, if not luckily it's a cheap item. The point is I just don't get why I have done the combine shipping procedure many times before and now it's not working. Anyone else or is it me? Thanks for  any help / reading my venting! \

Also, I do not require immediate payment and ask buyers to request invoice for combined shipping, this is working but rarely do they actually do this!

If buyer bought using 2 different id then no way of doing. I have been through this situation at least 3 times. Now I just cancel their orders and tell them to buy form same id so they can save shipping.

Thank you! This is what happened I can't believe I overlooked the username differences. Luckily these are low cost items but I am hoping it will still work out ok but glad I know for the future and that I now understand what the issue was.

Put this in your listing that they must but from same user id to take advantage of combined ship otherwise if you ship a few that has no tracking because you cannot add same tracking number to 2 different id then it will go against your stat. Some customer service state they will correct that but they do not. Do not listen to them if they state they will. I spoke to 7 different rep and it was never done even though they state it would be.
