I've enjoyed the same great experience with the RCBS service.
But personally, I wish they'd quit. I'd rather pay 20 or 30 percent less up front (just a guess) and then pay for any parts I loose or break later.
Of course that wouldn't help me now since I've probably already purchased 90% of the reloading tools I'll ever have. So I guess really I wish they had quit that policy 30 or so years ago.
If a company can send free parts to customers it means they built enough profit margin into the purchase price to pay for them. Companies do have to make a profit to stay in business after all.
