I have received the vouch.

The method is something I have not though of before and I think it will work, I buy from DHgate and Aliexpress regularly and will give it a try and see if I can get some free stuff.

It seems newbie friendly and simple to apply.

The method has no expiry so can be used forever, so you should get your money back from buying the method soon, depends on how many times you use the method.
