Nothing happened to Betslips, as far as I know. I checked out the new site and was very happy with everything, including the vast selection of games, the price, the payment options, and the ability to get a scanned image of the purchased ticket. When I evaluate a service, the most important factor is assurance that the ticket was purchased, and I don't think it gets better than that.
As for the comment earlier about them only taking Amex, I know that's just very wrong. They have a lot of different payment options, which is another reason I like them. They are easy to do business with.
So, if you're up for this kind of thing, or curious to see how it works, go to www.usamega.com, and click one of the colorful marketplace liks/blocks on the right.
The first order is totally free -- they refund the entire price back to you. So I'm not sure what the risk is in trying.
P.S. Powerball is now over $100 million -- a great time to check it out.
