Then you have no reason to complain. I always cancel orders from merchants who charge immediately while promising to ship on some undetermined date in the future or charge inordinate tax or shipping charges. Amazon does neither.
Amazon charges sales tax in my state, and it is 9.75%. Is that inordinate?
Amazon also will take up to a week and a half to ship something they claim to have in stock if the shipping is free. It's pretty obvious they are trying to give people a reason to pay for upgraded shipping service or Amazon Prime.
If and when I decide to buy this lens it will cost less than $2,000, be shipped immediately and there will be no taxes.
Adorama and B&H ship today, not tomorrow whether you pay for shipping or they do. On an item like this, the shipping will be free and fast and you'll get some discount points. And they truly charge no tax. Well, outside NY that is.
