. Note that you could buy additional bookmakers for a minimum of 30 days period. This means that if you buy a basic subscription for 7 days and you want to add more bookmakers immediately, you will have to extend your basic subscription with 23 days (30-7=23). If you decide to add more bookmakers after 3 days for example, then you will have to extend your basic subscription with 26 days (30-(7-3)=26).
