Today I sent the same request/question to these sportsbooks at approx 3:30 PM (EST):
1) BetJamaica
2) TheGreek
3) Stan James
4) 5Dimes
It took:
TheGreek - less than 10 mins to respond via email.
Stan James - just over 10 minutes to respond via email.
5Dimes about 15 minutes to respond via email.
BetJamaica has yet to respond and it has been a couple of hours now.
All but BetJam are very quick response times, why Betjam hasn't responded bewilders me.
