Six ways to control purchases
Each product demonstrates a different rule. Open an example, add it to your cart and try changing the quantity. Start a personal admin demo to inspect and edit all six rules.
Your admin sandbox lasts 60 minutes. Access ends at expiry; automatic cleanup follows. No real payments or external emails.

Sell in packs
Demo mug — packs of six
Choose 6, 12, 18 or 24 mugs. Quantities between packs are not allowed.

Set a minimum quantity
Greeting card — minimum ten
Start at 10 cards, then add one at a time: 10, 11, 12… Try reducing the cart quantity below 10.

Limit the quantity per order
Limited print — maximum two
Buy 1 or 2 prints. Try increasing the cart quantity to 3. This is a per-order limit, not a lifetime customer limit.

Try product variations
T-shirt — pairs in each size
Choose Small, Medium or Large. Each size starts at 2 and allows 2, 4, 6 or 8 shirts. Sizes count separately: 1 Small plus 1 Medium is not a valid pair. Try switching sizes, then changing the quantity in the cart.

Set a minimum spend
Workshop workbook — minimum spend
Spend at least €100 on this workbook, after discounts and excluding tax. Add 3 (€75) to see the cart warning and blocked checkout; increase to 4 (€100) to satisfy the rule. Other products do not count toward this example, and carts without this workbook are unaffected.

Define an allowed range
Notebook — between three and eight
Choose any whole quantity from 3 to 8. Try 4 or 7, then try going outside that range in the cart.
