I am very happy to combine postage and don't charge extra unless the price goes up due to the combined weight. I post worldwide with tracking - if you live outside of the UK and have purchased from me before I am prepared to post lower value items without tracking.
If there's no base shown in the picture and you want one, let me know and I'll try to dig one out if I can. Sadly I have no 32mm circular ones, but plenty of 20mm square or 25mm circular.

I typically pack items in cardboard boxes unless I'm 100% certain that the item is safe to send with extra support in a jiffy bag. I've collected wargaming figures since the 90s and understand the importance of good packaging!
I'm reluctantly scaling back the size of my collections and am slowly sorting out my ~very~ deep bits boxes/crates. My pile of shame is truly shocking, expect many oddities to be listed over the next year...
