For the last few months, I found SA not to be worth the time or money. The standard monthly rate just to be able to read or send emails had gone up to $100 (up from $75, I believe) -- and they had the nerve to say it was going to go up AGAIN (Who do they think they are, the cable company? haha).
I understand that it's supposed to be for those who can afford a SB, but above a certain point, the rates just got greedy & I'd rather spend the money on an actual SB or other things. I figured they might send me a better discount offer if I flat-out deleted the account, but they did not. (So if you're hoping for a discount, don't do that, lol.)
But at least I'm not wasting time on it, or on messages from guys who just happen to respond after I let a month's subscription run out. I did create an account on the lesser-used (at least in DC area) sugardaddy.com. Costs the equivalent of $10 each (one-time, per guy) to unlock an email from an SB but I only have to spend that if I've looked at the profile & think it's worth it. If SA would get less greedy and drop their monthly rate to something like $50, I'd probably go back.
