It can get quite pricey. For an extended date or longer I may take a $25 - $50 gift card and give it at the end if I the provider was great.

I usually get a Visa / Mastercard gift card where she can use it as she likes. I don't trust store gift cards anymore. The provider is screwed if the store goes out of business before she uses it.

Tips aren't really expected. Some gentlemen are kind enough to give them anyway and the range varies enormously. Whatever you think is appropriate should always be appreciated.

I don't tip on the first visit. If a second visit occurs, than I refer to the gift page on a lady's web site and usually select from the list.  If you are seeing someone who is offering a special, the difference between the regular rate and the special rate would be an excellent tip.  Good luck

Ive received 20 dollar tips and Ive received tips of several hundred dollars.

Its a very personal thing, some guys don't tip at all as a rule of thumb, others will bring a gift and still others throw a little extra cash into the pot if he had a good time on his date. You should do what ever your personally comfortable with.  

My motto about tips:
Never expected, very appreciated, ALWAYS remembered.

Since all of my dates are multiple hour dates, I don't think an extra fifty bucks is going to break me. I also usually ask for a dinner date, so springing for dinner is going to run another hundred. I think that's more than adequate. I will also sometimes bring a small gift, if I know what a lady might like.

Maybe this is why I have to go so long between dates.

I always give a $25 VS gift card (not worrying about them going out of business) and a candle set.  Have not met a girl yet that didn't like those gifts.

If you do a search on tips, you will get lots more input on this topic, it's been discussed many times, both here and the newbie board.

I was pleasantly surprised.
