Whew! After reading thru this whole thread I didn't find the answer to the question I had so here goes...
I'm hosting my first swap and I'm at the point where I'm swapping cards out and getting them ready to mail. Thing is that I'm noticing some pretty big differences in postage (relatively speaking). After checking out the USPS site it looks like some people mailed their cards to me as a 'large envelope' which is a cheaper rate and some as a 'package' which is more expensive. Of course this means that their RETURN envelopes have different postage too... in one case there are two envelopes EXACTLY the same size & weight but the postage difference that they put on there is about $0.85! So my question is... mail em all anyway and hope for the best or slap some extra postage on there for the higher rate (at my expense in some cases)??
Also... what SHOULD it be... a large envelope or a package??
