Right now you will not be able to buy single horse shoes or gelding with bonus credits while training. As you should already know...these items are inventory items now. For the time being I can send you bulk shoes or geldings upon request and reduce your bonus credit balance. Just send me a message here or on Discord and i will process your request. Cash purchases are still available as originally intended. You can also buy bulk items for cash at a discount from the bulk purchase page. This page can be found in the market section on the site.
