Hi,
I need too return a Mouse and some software too amazon.co.uk,both still sealed new,I gone through the web-site too get return label's and barcodes,printed them out and attach them.My question when I take the box too the post office,do I have too pay too send it back,like getting weighted or are they OK with return label's on them and just stick it in the postbag,advise really appreciated.Thank's in advance.
