that makes sense, but it's technically not a product, pretty much just labor. Certain states have loopholes that will allow you be completely legit and not charge tax. I don't know what states other than CA though.
this is what all elder people say in every generation. I'll probably say the same thing at your age. The world as you know if changes and it's not easy to understand how these people can possibly like what they like. The English language is changing, acceptable behaviors, etc. It's the way it goes whether we like it or not
I don't have an AMEX, but I accept them through my business. They are more difficult to deal with, but they seem to protect their users pretty well. I carry $5-$10k balance on my business credit card. I also pay off about that much each month, so even though I am carrying a balance, the $10k that was there on the 1st is not the same $10k that is there on the 25th. I am trying to accrue as many points as I can before April. I have two long trips I need to take and I am trying to not use any out of pocket money for the travel expenses.
a lot of cards do pay you to use it. I pay $75 a year for my card and accrue points. If i pay the balance of each purchase within 25 days of the purchase, there is no interest. I opened a new card in April, haven't paid interest yet and have 130,000 points, which is about $1300 credit towards airfare, hotels and rental cars, or I can actually choose purchases to remove from my history and the balance of those will be removed from what I owe in lieu of obtaining points. in 5 months I have made $1225 from Capital One. credit cards are not a bad thing if you understand how they work.
if aftermarket detail parts and photoetched parts didn't exist, I would have 0 interest in the hobby. I consider myself a car enthusiast, but I build because I have always been infatuated with miniature detail.
