If anyone doesn't like Bitsyncom's terms, it looks like contrary to their original messaging, they are allowing full refunds.
You just need to create a support ticket and put "REFUND" as the type of the ticket.

So far as I know... no one has taken them up on this offer even though some folks have been complaining about the shipment delays for months.

If you are feeling like you need to hedge... you can order the batch of chips and hope they arrive together.

If they don't arrive in your "window" of opportunity, submit a refund request.
Worst case, they either give back your BTC, or they escalate your order.... my guess would be the former.

I guess worst worst case is they don't ship your chips and they don't refund your BTC... but I don't think they could withstand the negative fallout of that option.
Just make sure to order from a wallet you control and can validate.
