You should go ahead and receive them. They are a lot of good information. Big nicks are good too, but each will teach you something different. Don’t be a hard head about the shipping time.
I am going to pass on them. I sent somewhere between 8-10 emails without a response. I know that PayPal also tried to make contact multiple times without a response. I would have waited if I was informed that there would be a delay, but I wasn't. I was left hanging and they had my $70. Sorry, but that is not cool.
