As a matter of fact, if you analyze the pricing range of the service, you can see that in comparison to 1 month membership, when you opt for a 3 months period of premium membership, you save up to about 40%, while when you pick up 6 months, you are likely to save up to 60%. So, there is actually no need in any discount. This money would be much better to be spent for the evening with a horny girl from the MegaFuckBook site of your choice.
