Buyers who have already purchased a portion of a bundle will receive a credit, in the amount of the Boom Store listing price of the already purchased item, against the total bundle price when they purchase the bundle.
Your proceeds will be based on the final price after credits, not the full bundle price.
Example
Sasha purchased Decimal Place Value: Expanded and Standard Form from I heart 4th grade for the then current price of 250 points.
After using it for a week, she and her students love it. She decides to purchase the 5th Grade Decimal Bundle for her classroom. The bundle price at the time is 1000 points.
When she goes to check out, her price will be 750 points.
She tells the other 5th grade teachers about how much time she saves using the product when teaching decimals and how engaged the students are. Matthias signs up for a Boom Learning membership and buys the 5th Grade Decimal Bundle. He pays the then current price of 1000 points.
I heart 4th grade receives her portion (less service fees) of $2.50 (initial deck purchase by Sasha) + $7.50 (bundled price less credit for deck purchase for Sasha) + $10.00 (Matthias' bundle purchase).
