My son and I want to attend one of the Baseball Think Tank camps this summer. When I started looking at the dates and which camp would work best, the price was $1600. But a week later, once I was ready to sign up, the price had gone up to $1900. Theres is a place on the signup form for a promo/discount code. Does anyone know what that might be? The $1600 price tag was pretty steep for us to begin with, and the extra $300 makes it even more so. Thanks.
