I tend to buy only from my local area so I collect most things.
Some Sellers will be willing to wear the risk too though.
We'll see.
The thing is though, that if they overcharge for postage, it will be reflected in their feedback anyway, because they cannot leave negative feedback for buyers in retaliation anymore which I think is awesome. There have been times for me where a transaction has been AWFUL for me as a buyer, but I've had to leave positive feedback because I didnt want falsly negative feedback left for me.

BJ has had a MUCH better day today, only getting crabby when he was overtired!!
The Chiropractor moved his tummy down, and diaphragm across, both of which should either fix, or at least help the reflux...the rest of his issuses should now settle.
And yes, I tried Zantac and nearly threw up!
We had him on gaviscon, and thats how all this started, it constipated him terribly (and I'm talking golf ball size, and solidness!) so he was taken off that and put on Zantac.
