Volume pricing discount

I am selling raffle tickets in a shop using HikaSerial - it is a great solution, and the attachSerial plugin with an emailed image is fantastic.

However, I have a pricing issues I can't resolve. I would like sell tickets for £2 or 3 for £5. So far so good. I have achieved this with a coupon flat-rate £1 discount with minimum quantity of 3 items.

What I'm having trouble with is applying a £2 discount when 6+ items are bought, a £3 discount when 9+ items are bought - and so on in multiples of 3.

Thus my pricing would look like this:

# tickets sold / individual price / cumulative price

1 £2 £2
2 £2 £4
3 £1 £5
4 £2 £7
5 £2 £9
6 £1 £10
7 £2 £12
8 £2 £14
9 £1 £15
etc

This is a bit different to normal volume pricing discounts. Is there a way to apply a stepped discount on every 3rd item purchased, but not the intermediate numbers?

I tried setting up multiple coupons to autoload in the cart for a £1 flat rate discount on with minimum quantity 3, £2 flat rate discount for minimum quantity 6, etc, but it only applies the 3 item coupon even if I have 6 or 9 items in the cart.

There must be an easy way to do this?

Many thanks

I've worked out that the higher level discounts work correctly if I disable the lower ones - so it seems that the lower discounts are over-riding the higher ones in some way.

Is there an order/hierarchy governing which coupon takes precedence?

Thanks

Hi,

When many coupons are allowed for one cart, the cart should take the highest coupon into account.
Recently changes have been made, and it seems that this is not working as expected.

I have added on our TODO list to correct that as soon as possible. High priority
