There are 2 meanings for when the "Pre-Order" button shows up on the product page.
If the product hasn't come out yet, the pre-order button will be displayed on the products page. This will allow you to place an order for the item in question. Saving that item for you for when it comes in. You don't have to pay ahead of time, unless you want to. (Just make sure to select pre-order at check out).
If the product has already come out or has been out for a while and we at Mr.Muffin's Trains run out of the product, the pre-order button will become available allowing you to request this item. Please contact us via e-mail or call to find out if we can still get a hold of the item in question, since the manufacturer might be out.
When our kids were little, we would make up stories about the Muffins, and most jokes started with Mr and Mrs Muffin. When my son helped me set up my eBay account in 2000, he set it up for me as MrMuffin'sTrains - and it stuck!
Both MTH and our system are not synced together. This can lead to MTH stating that we have a product in hand when we are completely out. You are welcome to call or e-mail us to verify if the product is still available.
