the only problem is if buyers are paying through paypal sellers need to send with  tracking and

lodge over the counter you need proof it was posted

some send in envelopes but if it doesnt arrive they need to resend another or refund

it can be costly

i mainly use trackable satchels or wrapped parcels and always put over the counter and have them scanned

not had a problem with any of these

but i once sent an item in an envelope it didnt arrive the buyer waited extra time,i had to resend at my own expense

in a trackable satchel which i had scanned over the counter and yes this arrived ok

never saw the envelope one again lol

so its up to each individual seller

my buyers dont seem to be put off by my postage costs
