Forgot how much postage to use...

Edit:
I found my cheap scale thing and it said it weighs about 4 ounces and I checked the USPS website.
I've decided on 3.60 in postage.
A MOD can delete this thread.
Thanks!

Hey everyone.
I haven't sent out a request for a few months and like an idiot, I forgot to write down how much postage I usually use.

Here's what I'm sending:
-10x13 envelope
-10x13 sase
-Letter of request
- Two 8x10s
- Cardboard so the envelope won't bend.

This will be going from Chicago IL to the UK.

Thanks so much!
