Many sellers offer 30 days money back guarantee for the product they sell. This is supposed to make you feel that you have nothing to loose if you try the product and don’t like it.
The reality is different. In some cases, the seller will simply not answer your eMails, or will not want to return you the money. Especially if the seller uses PayPal, you’ll not be able to get your money back in some cases and the complaints will not help.
I have personal experience with this kind of situation. I even escalated the complaint, but I did not see my money back.
Beware of sellers who are not PayPal verified : sometimes they just take your money and run.
What can you do to protect yourself? First of all, try to contact the seller. Ask him a simple question about the product. For instance, ask him what he means by “instant download” – instant, almost instant or instant after verification. If he doesn’t bother to answer your eMail before you bought the product, chances are remote that he will give you your money back. Also, pay attention to his answer – how helpful and polite is. I’ve had the unpleasant surprise to have my eMail bounced back – his eMail address was no longer valid.
Second, try to search on Google for a review of that product and / or that seller. Sometimes, you’ll read details you’ve never thought about.
Last, but not least, try to search on Google if that product is available free. I once wanted to buy a book from a reseller site, and I found out searching on Google that the original seller was given that product free.
