Cash for gold shops and websites have got quite a bad reputation with some people. They are said to not always offer the best money for the items given. However, you have to remember that they need to make a profit and it is unlikely that you would ever get the market value for gold that you were selling. However, it is still always worth getting a number of quotes before you decide who to sell your gold with.
A site such as http://www.britishgoldrefinery.co.uk/can be extremely useful because they will allow you to enter the weight of your gold and will give you a price. You will then know exactly how much they will pay you. If you go to a selection of sites and enter this information, you will be able to work out which one will give you the best payment.
It is worth being very sure about the company that you use. Make sure that you trust that they will not only give you a good price but pay you at all. Sending gold away is a risk so make sure you insure the parcel when you post it and make sure you are happy with the company. Find out more about them by reading their website and reviews of them and even ask around to make sure that you are confident. Most companies are trustworthy, but the few out there that are not, make it necessary for us to be cautious.
