CRC gave me a voucher for £100 as a warranty payment, it runs out in 2 days.

If I buy something and return it at a later date using the 365 returns will I get the voucher reissued again?

Yes, If you return something for a refund they will refund you back the same way you paid.

Hopefully that one wont have 2 days left on it too

However going by recent experience expect it to take around 3.5 months to arrive and then dumped in the blue bin (yes they use yodel now). Shame.

Make sure you keep proof of postage, as they may lose the returned item and and keep your money.

Yep, yodel **** left the cardboard box tucked behind the recycling bin on recycling day
