The same usually applies on percentage discounts - if the offer was buy one, get one at 20% off, in reality each item would be 10% off in so far as how the discount (and any subsequent refunds) are handled.
Ran out of time to edit, but just wanted to clarify this bit a little more - if the promotional items are different prices (eg one is $50 and the discounted item is $25), the discount is applied across the items a little diferently.
eg In the case of there being a 20% or $5 discount the $25 item, it's apportioned according to the original prices, so on the $25 item, a discount of around $1.67 will be applied, and the remaining discount of $3.33 will be applied to the $50 item, which is why eBay allow sellers to specify whether the discount is applied to the one item, or all of them.
