This might be a strange question - and quite possibly a not very clever one 
. But it has to do with licences.
I have a client that is using the same theme across 3 different domains (3 different language versions - all looking the same).
I am purchasing the item 3 times.
I will be copying the code from one wordpress site to another without uploading the theme.
Do I need to upload the actual code that comes with the download when you purchase an item - or is purchasing it and therefore having multiple licences enough?
Thanks.
