I’m setting up a Data Recovery Service Request form in tally.so for my business, but I’m struggling for approximately 4 weeks to implement my bulk discount pricing model. Here’s the pricing and discount structure:

Pricing per Device:

Android/iPhone: $225

USB Drive: $125

Memory Card: $100

Internal/External HDD: $275

Internal/External SSD: $350

Digital Camcorder: $250

Bulk Discounts:

2–4 items: 5% off

5–9 items: 10% off

10+ items: 15% off

I’ve tried multiple approaches in Tally.so (conditional logic, calculations, etc.), but nothing seems to work. How can I set this up so discounts apply automatically based on the total number of items selected?

Ideally, the form should:

1. Let users select multiple devices (with quantities).
2. Calculate subtotals + apply the correct bulk discount.
3. Display the final price dynamically.
4. Any guidance or workarounds would be greatly appreciated!
