Time Taken To Grant Credits on Xpango.
Xpango were not the quickest when it came to delivering our gift. This was mainly down to the problems Xpango seem to be having with answering their emails in a timely fashion; we were required to confirm our gift order and delivery address via email when placing our order, which took several attempts. Once Xpango had confirmed our delivery however, we received our gift one week later.
Once your account has been verified, you will usually receive your free gift within a week, which is very good. We were especially impressed with Gameconsole Giveaway as we were able to obtain a PSP within 4 weeks of registering with this site.

Xpango Credits System: Offers Available and Xpango Clix
Xpango are somewhat unique in that they offer a variety of methods for gaining credits to put towards your free gift, and allow you to complete as many of these offers as you wish in order to build your own credits.
They host a number free offers, including Lovefilm, Blockbuster, EasyCinema, Music ETC, Bidz and My Movie Stream, all of which will earn you one credit for participation; there are also a couple of offers worth 0.5 credits from Celldorado in the form of mobile phone ringtones and screensavers. It would therefore be possible to earn up to 7 credits to put towards you free gift by participating in all of these offers.
Xpango also have offers which will earn you between 2 and 4 credits for participation. Below is a summary of the offers available and the number of credits you can earn:

Selling Xpango Products Using Auction Templates
As well as completing offers, you can buy mobile phone accessories, such as ringtones, card readers, sim cards etc, which will earn you 1 credit for each purchase. In our opinion however, these are not competively priced and are unlikely to offer any appeal to those seeking credits. A 7 in 1 card reader on Xpango, for example, costs £15.99, whereas most retailers sell them for around £8 - £10. If you are buying the item solely for the credit, you would be better participating in one of the paid offers, such as Mecca Games, which will cost only £10 for 3 credits.
Xpango also suggest that you can sell their mobile phone accessories on auction sites such as Ebay to earn yourself credits. They even provide a number of html templates for you, so you can simply copy and paste them into Ebay to create an instant listing. The way the system works is that you post a listing advertising a product, e.g. the 7 in 1 card reader for a 'buy it now' price of £15.99. When someone buys the card reader, they pay the money into your paypal account (or however you normally receive payments). You then use this money to buy the card reader on Xpango, and you enter the delivery details of the person who bought the card reader. They are then sent the card reader they paid for on Ebay, and you receive the credit for the purchase.
In theory this is a very clever way of obtaining credits, however in practise we were unable to sell any of the items we posted on Ebay. Again, the accessories are not competitively priced, and are therefore unlikely to sell on auction sites, unless you sell them at a loss. We have tested this method of gaining referrals repeatedly, and have yet to generate a single credit.
