Welcome! The deal is this: Buy any two kits shown on this page, get a third kit of equal or lesser value for free.
The shop software is not smart enough to apply the discount on its own, so I will be processing refunds manually for your third kits.
If you have a question about a kit, I suggest purchasing it first and then emailing me. I’m happy to cancel an order for you, but the kits are going to go fast, and I don’t want you to get cart-jacked or otherwise lose out while you’re waiting for a response from my side of the world.
Wishing you happy shopping!
