why Fiverr is deducting an amount for first-time promotions for creating a custom offer for the buyer on that particular promoted gig when in the first-time buyer promotion guidelines it is clearly stated that
"
Promotions will only be applied to the active Gigs that you select. Note: Buyers can’t combine this promotional discount with Custom Offers, Seller Coupons, or any other special rates. "
Here it clearly states that the promotion will only be applied when bought directly from the gigs, not on the custom offer or any special rates.
