This is almost a scam with Paypal. The voucher can only be used on eligible purchases from stores that accept these vouchers. Almost no store accepts them as they're technically not a voucher but a discount code, which is why most stores don't accept them as they have the potential to give large discounts on products.
You will find almost no store accepting them. This is also why the use by date is around 2 years as it gives you plenty of time to potentially find one store that accepts them in the 2 year period. The voucher is marketed as being a general voucher that can be used on most/all purchases when it's not the case at all. The shopping voucher was never an option until Paypal took over Honey and added this. This also means that Paypal/Honey don't have to fork out money on real vouchers and can offer this, in the hopes people (myself included) think they'll be able to get a £ discount on their order through paypal. You can't and so Paypal don't have to spend money giving you gift cards, the transaction is final so you can't reverse it and paypal don't make a loss on anything as the voucher cannot be spent due to no stores accepting them.
I've checked around 100 stores so far and not one accepts it, ebay, etsy, zavvi and so on do not accept these vouchers and i'll be very surprised if I find a store in the next 2 years that does.
