$10 off first purchase automatically

[DrByte]

You could set up a $10 coupon, tie that to new customer signups in Admin->Configuration->GV Coupons, and then remind them during checkout to check for that coupon code in their email. This would help confirm that their email address is indeed valid.

Or just create the coupon and tell them about it on the payment-selection page.

Or write custom code to calculate whether this is a new customer and apply a discount, making sure to display all the totals and discounts appropriately, and take taxes into consideration.
