Coupons and Discounts

An interesting issue has just been raised.

Regular customers get a voucher giving them 10% off.
However, a short period special 5% discount is also running.

Don't want to give regular customers 10% off the discounted price.
An option to ignore the discount if the customer enters a voucher worth more might be useful.

Another solution in this case might be to use ACLs - put regular customers in a regular customer ACL group which automatically gives them a 10% discount.

Been thinking about this issue a bit more.

Could an option be added to (say to a coupon) so that:

(a) Discounted price is shown in shop / cart / checkout by default (as current)
(b) Customer enters a voucher (as current)
(c) Non-discounted total price calculated.
(d) Voucher discarded if non-discounted total price minus voucher is less then discounted total price.
(e) Voucher used and discount ignored if non-discounted total price minus voucher is more than discounted total price.
Prices in checkout changed to show non-discounted prices.
(f) Need to delete voucher(s) and start again if customer goes back into shop and adds another product to cart.

Products with different discounts / vouchers should work in the above scenario.

Confusing for customer they put a £90£100 (i.e. 10% discount) item into cart and then enter a 25% voucher.
The item price changes to £100, £25 voucher discount shown and total price of £75 shown.

Anyone have other thoughts on this subject?

Thanks for the tip, useful to know if in a corner, but would prefer to avoid for now.

Maybe not a good idea having a 10% off everything promotion and giving out 25% vouchers off everything at the same time. Need to find out where this idea is coming from and what they are really thinking. If the 25% is for selected customers then ACLs could be the way to go.

One solution is to have 2 vouchers.

VOUCHER1 - say for 5% with auto-load in cart option enabled.
VOUCHER2 - say for 10%.

On checkout a customer wishing to use VOUCHER2 could delete VOUCHER1 and enter VOUCHER2 instead.

As the discounted prices are NOT displayed, would require shop owner to make sure the offer is prominently advertised throughout the site.

On testing this on the demo site found that I could not delete VOUCHER1 and enter VOUCHER2 at the checkout. Bug?

Also, untested, what would happen in the following scenario:
Both vouchers have auto-load in cart enabled.
VOUCHER2 is only enabled for certain customers.
Will VOUCHER2 be the one to get automatically loaded?
What will happen if VOUCHER2 is worth less than VOUCHER1 (no ACL on VOUCHER1).
Will VOUCHER1 then get auto-loaded instead of VOUCHER2?

Have a possible solution to the 5% product discount and 15% voucher issue where the shop owner wants to limit the total saving to 15%.

Products displayed in shop in normal way with any applicable product discounts.
For instance customer buys £100 worth of goods for a total discounted price of £88.
They then enter a voucher which gives them UP TO 20% off the NORMAL PUBLISHED PRICE.

Without any product discounts this would be worth £20, but they already have £12 worth of discounts.
So the voucher is only worth £8 - that is the value that gets displayed and used in the cart.

Similarly if the voucher gave them up to £30 off (as opposed to a percentage), then it would be worth only £18.

Would require some sort of 'Voucher off published price' field on the discounts table - default would be existing behaviour.

Does this seem like a reasonable solution, one for the wishlist?

Thanks.

Hi Nicolas, did this make it into release 1.5.3?

Any target date / release for this please?
