Promotion product price settings

[Summerr]

Hi there,

The unit price of each product will change according to the number of products purchased.

I have some products with different prices, I would love to know is there a way to make this happen or any Apps can help me with this.

For example: 1 cup is $20 / 1 plate is $25 / 1 cleaning cloth is $15 / 1 soap is $10

1.  If I purchase 1 cup + 1 plate + 1 cleaning cloth + 1 soap, the quantity is over 4, so each product price will be $15 / $20 / $10 / $5, instead of only showing the total price $50
2. If I purchase 3 cups + 3 plates + 3 cleaning cloths + 3 soaps, the quantity is over 12,  so each product price will be $10($30 in total) / $15($45 in total) / $5($15 in total) / $2.5($7.5 in total), instead of only showing the total price $97.5

There are different tiers of discounts, so separate prices can help users better understand the huge discount we offered.

The total price is fine, but if separate price can be showing, that would be better, am I make myself clear?

Please help! Thank you in advance.
