Small claims is valid even for a penny ...
I issued a Small Claim against a well known sports wear company as they refused to replace a pair of "waterproof" walking shoes that leaked after 8 months .. stating that their policy was to refer the goods to the manufacturer for examination. I stated that my policy was to obey, and use UK Law, and that they had 14 days in which to replace or refund the goods, as they were unfit for the purpose for which sold, and sent the shoes to them recorded delivery.
On the 15th day I submitted a claim on-line for £54.99 for the shoes, and the postage costs, which automatically had the court costs added to it, came to around £80 if memory serves. On the 17th day, and before the claim had been processed to the shop, they phoned me to "discuss" a way forward where they would be willing to pay half the postage fees to return the goods to the manufacturer for examination. "Gobsmacked" is how I would describe the reaction of the manager when I informed him what I had done.
It was obvious that he had waited over 14 days simply to be awkward... as he initially said they had not received the shoes... when I quoted the date, time and name of the person who signed for the package he tried to back down ... 'twas a tad too late ... on the 21st day I received a cheque for the full amount, refund, court fees, postage costs.
For the sake of the court fees it is worth taking these guys on IMHO .. I've not lost a case yet ..
