"DEBOSS is currently offering free samples and free delivery of its sauces to residents of London, United Kingdom.

Unfortunately DEBOSS lacks the resources to make this offer available to persons outside of this region. However we would love to accommodate everyone, so if you live in the UK but outside the London area, we are willing to supply the samples, if you are willing to pay for the postage charges.If you're into exotic spicy food you wont be disappointed."

It's £2 for postage for two samples if you're not in London, haven't signed up for it myself but thought it was worth sharing
