Sorry I missed your post.
Yeah, a 1:1 will do. I'm not going to use them so will let other benefit from a bit of a discount.
I've just got another 1000 wrapped up and ready to send to a guy so I have 400 left.
Sorry for the delay, been a busy week at work!!
Postage for 1000 looks to be about £7 with royal mail medium parcels guaranteed next day by 1pm.
Still got some left so get in touch if you want some sending.
