Multiple Bundle Discounts and Discount Progress Bars

[hollypie002]

Hi, 

I'm looking for a way to allow customers to get a bundle discount when they buy multiple products, for example when a customer adds 3 pairs of socks to their basket they get £3 off and when they add 5 they get £8 off etc. 

So 1 pair of socks = £6

3 pairs of socks = £15

5 pairs of socks = £22

Ideally I would like it to be a monetary discount rather than a percentage and be able to have multiple bundle discounts, so do the same for hats, scarfs etc but have them all be separate amounts. 

I would also like to be able to add a progress bar which says something like:

Add 1 more pair of socks to make them £5 per pair and this changes based on the quantity which have already been added to cart. 

Ideally this would work for multiple items, so there would be a progress bar on the product section page of each type of item which do not interfere with one another. 

Hopefully this is possible 😂 Thank you for your help!
