I only want customers to have the offer when adding more of the same product for the certain number of items they add to their cart from the offer: Example:

1) Buy 2, Get 5% off "total purchase price"

2) Buy 3, Get 10% off "total purchase price"

So anything over 3 and/or whatever number I set the offer at, it needs to go back/stay at regular retail price. So when I add more offers for my other products, it needs to go back to regular price. Another example:

If I offer buy up to 3, 4, 5, or 6 for 15% off total purchase price, the discount will not be offered over my specified offer.

Also for the drop down, instead of "each", I think "total" or "total purchase price" would be better for the customer. As it looks now, it may be confusing to say "each" as the customer will think "each" item they add to the cart will be the % off instead off % off "total" price.
