You will soon - on March 4 - be able to purchase Surfulator for $39.50 at Bits. In the past, I'd have killed (well, maimed, anyway) to get it for that price. Since I couldn't afford it I bought Ultra Recall at a reduced price only to learn, here, that it is no longer being developed. However, I can't really complain as I got it at a VERY good price. I'd like to try Surfulator but having already paid for the other program and being very strapped for $ these days it doesn't make sense to buy yet another license for yet another very similar program. Oh yeah, AND I am a Firefox user.
Regarding pricing: Any developer can charge anything they wish for their products. A buyer can only pay or decline. As shareware prices rise, I must decline more and more. $80.00 is a lot of money to some of us. With the trend toward high upgrade prices and limiting upgrades to the one year mark, I have (sadly) accepted the fact that the version I pay for is the one I will be keeping - forever. Anyway, to my way of thinking, upgrades are not always improvements and more than once I've gone back to a previous version that I was happier with.
