Multiple Variations

I would use a coupon to reduce the price, or there is a quantity discount plugin I’ve used. I think it’s called bulk discounts or something like that.

As far as selecting multiple product variations from a single page, you could use gravity forms and the woocommerce plugin to do a custom order form. You would just include 5 lines, one for each variation. So you would create a product like “5 Fragrance Combo” and sell it for $12 bucks and then add a gravity form where the client picks the 5 fragrances. It will not relieve inventory of the 5 fragrances though. But you’ll get an order for the pack of 5 with descriptions for the 5 selected.

The easiest thing to do would be just send them back to the same page after add to cart and then they just have to change the fragrance and hit add to cart again and then either have them apply a coupon or use the bulk pricing plugin to calculate the price.

Product variation 1 would be 1 for $3
Product variation 2 would be 5 for $12
Then have a look at “add-on” plugins to allow fragrance selection:
