I got a vouch copy so here is my honest review:
The guide is very complete and detailed, it includes a long FAQ that helps a lot, and the guide explains EVERYTHING, its the most complete guide I've ever seen about this topic (and I've read a lot of different guides about refunding)
All the process is explained in detail and you will know what to do step by step, including opsec so you won't have any issues, but OP also offers support if you have any question.
There are a lot of different method explained in the guide, including all the additional info you should know about them.
The guide also includes a good guide about paypal refunds which can be very useful to refund a lot of stores since paypal processes your refund, not the companies themselves.
I highly recommend this if you want to learn refunding, you can even open a refunding service to profit from this and get your investment back in no time
