CartBot: Gift with purchase

Loving this app so far! We needed to add a free backer plate to every face plate ordered on our website. We also had to add a handling fee for face plates and rock guards due to the extended length of the product (96") when shipping. We added a Bot for face plates with two add-ons (backer plate/handling) and a Bot for rock guards with one add on (handling). This prevented conflicts between Bots and eliminated constant cart refresh when processing both types of add-ons. Took me a minute to realize I could have more than one add-on in a Bot, but now it is working seamlessly! Thanks, CartBot and Henry!
