We can accommodate all types of offers such as "first 50 orders come with a free sticker" however this needs to be set up in advance. Please bear in mind if you have a signed version of a product then it needs to be set up as a separate product/SKU to the unsigned version.

We recommend creating a bundle so the stock allowance is taken in to account, you can hide the bundle contents using CSS so that for the customer it appears as though they are purchasing the standard product. Then when stock is exhausted you can inactivate the bundle format and have the standard version on sale.
