Hi Billy, it's something that normally goes on, they offer you a package, then you mention your price, so they back off, they will then go back to the writing board and have a think.
What they want you to do is accept their initial offer, don't worry, they will offer you another package, so it's sort of deciding on a price, however, if you keep rejecting their offer then that's not good.
Have a rethink about what you want, it maybe a little less but mention it to them.
Don't be afraid to do so and good luck.
Geoff.
