Not long ago Amazon didn’t collect sales tax for deliveries outside of Washington state. Now they collect it in most states, though if you buy from 3rd party sellers on Amazon you can avoid paying it.
Currently B&H only collects sales tax for orders delivered to NY. However they are opening a warehouse in NJ and will be collecting sales tax on orders delivered to NJ starting tomorrow.
If you live in NJ and are on the fence about purchasing a big ticket item, now is your last chance to order without paying sales tax.
Technically, most states ask that you self-report items that you didn’t pay sales tax on.
Don’t forget that if you have a Visa business card, like a Chase Ink card, you can enroll in Visa Savings Edge for an additional 5% automatic cash rebate at B&H.
