Although I agree that there seems to be issues with PPC's shipping I also want to toss in that where you live is part of the costs.
I'm in NH and PPC's is in Florida.
2 days to me by USPS priority mail and what I've been charged is right with what the costs should be.
You also have to remember that shipping isn't just a postal charge. Those little bubble mailers cost $1.00 each, cardboard boxes cost like you wouldn't beleive.
You can easily pay $5.00 for a cardboard box and all of this has to be included in the shipping costs.
Then add bubble wrap. Have you priced it recently?
Sealing tape is $3.00 a roll and it isn't that big a roll.
Amazing how it can all add up.
