No, you can not combine your receipts into one request. All receipts should be registered separately, one by one.
If you have Tax-Free forms or shipping documents mentioning multiple receipts, please register each receipt separately. You can upload any Tax-Free forms or shipping documents to each receipt.
There is one (1) exception:
If you have a receipt with an amount below the minimum spend threshold, you are allowed to add this receipt to another receipt from the same store. Please note the items must be bought on the same day. The store address and purchase date must be identical for both receipts.
