Trn/trx number, what on earth?

Question

I have recently bought a sewing machine from argos, nice machine and i was supposed to get a free bag with it via leaflet, HOWEVER, it has asked me for my TRN/TRX number. I've emailed argos and called them asking what I am meant to write in this section, unfortunatly, my only reply was "You're TRN/TRX number"

Also, I need to know my serial number, they claim it is on my machine...Yet again can't find it, can anyone help me, and does anyone own this sewing machine http://www.argos.co.uk/static/Product/partNumber/4600107/Trail/searchtext%3ESEWING+MACHINE+TOYOTA.htm

And know where the serial code is.

I really need help times running out on the offer and I need it for when I'm at my boyfriends house/best friends house in the summer!

Thanks!

I think trx could be short for transaction. See if there is a number on your receipt.

Serial numbers are often on a sticker or plate on the bottom of a machine.
