Sometimes eBay can be a bit grumpy when it comes to requesting invoices when using the app.  Doing "add to cart" means I can send the invoice whereas "buy it now" looks like a heap of postage and that I can't adjust.  If  you do have any problems with the "request total" please let me know.

I type that and then eBay finally fix the issue, lol.

And, again, if you have any questions about this please do not hesitate to ask.  Thank you very much for looking and please check out my other items I have up for grabs because, on most occasions, I'm able to combine postage.
