this happened to my daughter, what would you do

she purchased 3 separate small items  that was $4.00 each with free postage that went into a large letter $1.40  very light weight .

now what would you do as a seller they can all fit and weigh in a large letter under the 125g weight  would you send it in 1 large letter or separately  or send it in 1 large letter and give a refund for postage  or no refund 

---------------------------------I personally would probably send it in 3 separate envelopes but that would be because there does not appear to be any tracking. I figure that a buyer might claim one as not received but it would be dodgy if they then tried putting in 3 separate not received claims.

As a buyer though, my only expectation is that my items arrive safe and sound and in a reasonable time frame, so if a seller sent all 3 of my purchases together I might think-hmm, they made a bit of a saving on postage, but if their postage was listed as 'free' I wuldn't feel i could complain or receive a refund.

Basically, I am just happy to get my items.
