[Closed] may be swapping my guitar.some questions about posting it.

i may well be swapping my ibanez s 420 wb for another ibanez CMM1.

my question(s) are how would i go about sending it without a credit card?

the gentleman recommended me http://www.interparcel.com/ to post the guitar with (he is going to send me his hard case (as i only have a gig bag for it,was going to give him/post guitar in the gig bag).

my question is would i be able to pay the postage when the delivery man/woman comes to pick up the guitar? also is there anything else i may have forgotten/need to do (this is my first time i have ever swapped/sold e.t.c online so don't want to mess it up,the gent receive my guitar in a million pieces e.t.c 😳

thanks 🙂
