I have been buying with the pre-order pricing option from BMS for several years. The way it works is, you place your order before the end of the current month and BMS then makes one big order from Aerotech on the first of the following month. You have to wait until Aerotech ships that big monthly order to BMS and then they in turn ship out the individual orders to everyone that placed their pre-orders with BMS. This can save you a good amount of money, if you don't mind waiting anywhere from 3 to 6 weeks typically. I make one major purchase in the spring for all of my Aerotech needs for the upcoming flying season. This way I only wind up paying for one hazmat shipping fee per year. This year alone I bought around 20 reloads in the I impulse range, but have just recently gotten my Level 2, so some J motors will be next. Bill S. of BMS has always taken good care of me, and I personally recommend him as one of my go to vendors. I also burn about the same amount of CTI reloads, but I get them from our on-site vendor, which is Robert and Gloria of AMW/ProX. I am also a Wildman club member and have purchased from Tim several times, but mostly during those insanely good Black Saturday sales.
