Park and Variety are the founder members of the CPA (Christmas Prepayment Association). The Post Office are also a member.
You can find the Code of Conduct here www.cpa-advice.co.uk.
The CPA was set up in the wake of the Farepak debacle in 2006 and has been trading for almost 6 years now.
Member companies must keep their customers' monies in at least 50% independent trust accounts which are controlled at least 50% independently outwith the member company. When the time comes for the money to be released ie to pay for vouchers, hampers, white goods etc, the Trustees must authorise the release of the monies.
It is incorrect to say that "poor people" save with these types of companies. Actually sensible people save with these types of companies. The money is locked away and you cannot get at it until you have paid in full. Furthermore, given the fact that interest rates have been so low for so long now, you get more in commission from Park and Variety than you would saving in a bank account.
People who save with Park, Variety or the Post Office are sensible as they are saving for a debt free Christmas. Once their vouchers, hampers arrive they basically can go shopping, do the wrapping and settle down and enjoy Christmas.
In short, your money is safe with companies who are members of the CPA.
For the avoidance of doubt, vouchers with supermarkets are NOT regulated and supermarkets have been asked to regulate same but they refused because there is no legislation in place to force them. Also gift vouchers are unregulated so if a company goes into administration (like Comet did) the vouchers will more than likely not be accepted.
