<prompt> Human: Amazon has the strangest way of processing transactions. Ive been a Prime member for five years and still cant figure it out, despite receiving 5 orders per month from them on average. I use YNAB for my budget and transactions. In YNAB, I can separate a single transaction into multiple categories. The other day, I ordered a new scratching post for the kitty and a dish scrub brush. Obviously not the same category. So after placing the order, I go to the detailed view and record the individual amounts of those items into YNAB for those categories. Reconciling my credit card account right now, I cannot for the life of me figure out how Amazon came up with the amounts they came up with to charge me. They do even out, but I always have to go back and change it in YNAB.  <response>: Amazon charges per shipment, so if scratching post and dish scrub ship together, but cat food ships separately, youll get 2 CC transactions for those two shipments.
