Gift Vouchers and Recently Viewed Products

Hi all,

I am currently working on a project where my client requires the use of gift voucher codes that can be redeemed during the checkout to apply a discount, is there a module out there that will do this or is this built into isotope somewhere and I am missing it?

I have tried using the rules and coupons section but it doesn't seem to offer the functionality that I require.

The other functionality that is required by this project is that the customer can see which products they have recently looked at much like many other online shops offer, again is there a module that includes this functionality?

Any help will be greatly appreciated,
Thanks,
Ste.
