If you find yourself wanting to participate in a Price Drop Sale and a Marketplace product. You will need to purchase these items individually. This is due the functionality of a Drop Sale.
Every time a pricing milestone is met the price drops, this means that anybody who has committed to the sale prior to the price drop gets a refund. Therefore, we need to be able to handle this process independently of all other sales.
You will need to process seperate orders.
1 for your Drop Sale item and 1 for your Marketplace orders.
