I tend not to restock boards until there is demand so if you want an out of stock board please let me know and I'll reorder.

Please email me at acorn@oddys.plus.com) to confirm availability (as I also sell on eBay, where stock levels are more accurate) and I will send a PayPal invoice for payment.
