We will consider the eligibility of your order only at the time of your order being delivered; eligibility depends on the challenge or task’s criteria.
For example, if a challenge task requires one to make an online purchase with $80 minimum spend:
Mary makes an online order worth $85. However, $8 worth of items from her order was later found to be out of stock, resulting in the amount paid to be only $77 worth of items. In this case, Mary’s order will not be eligible to complete the challenge’s task.
