Should be fine. Be sure the SKU and model number is what you want (compare it to the manufacturer's website if you can) and remember Amazon is good about letting you return things. Not so good on paying taxes, but good for returns. :)

I got my current faucet from Amazon and my previous from faucet something.com. Sometimes it's just easier.

My experience is yes and no, I bought three faucets on Amazon about 6 months ago, the Kohler Forte came exactly as the specs from Kohler indicated, the two American Standard bathroom faucets (which were listed in the specs for that model as having flexible stainless steel lines to the sink drain assembly) came with plastic lines (like you'd get from the Big Box stores).

I worked so hard to find faucets that had no plastic at all and was quite disappointed when I saw those, but in the past 6 months nothing has gone wrong so I'm just keeping my fingers crossed that nothing changes in that regard.

Check the manufacturers part number. If it's the same, then the quality is the same. For example, I bought a toilet from Lowes. It had a different part number but was way less than anywhere else. It turns out that the Lowes product was the same toilet, just a cheap plastic seat instead of the soft close that's in the specs on the manufacturer's web site. On inspection, the part numbers were different. Same base number, but some digits between some dashes were different. I ended up buying a 3rd party soft close seat. Instead of the $75-$100 savings, my net savings was really only $25-$50. Still a savings though.

This is my take... The Big Box stores order from a vendor X number of units for all stores if the price they want to sell the item at can be met. The vendor needs to make a profit also,so they figure a way to make the product work for the BB store if they have too. This may result in a lower quality product. I'm not say all vendors will do this, some will stand their ground, letting the buyer at the BB store worry about the margins if he wants too.
Before I retired I was a sales representative to some pretty major retailers. I didn't sell directly to the BB stores that I'm speaking of but I listened when I heard a conversation between a couple of reps who did.

Amazon is a whole different type of retailer and while they do have products that ship from their warehouses, they also sell products from independent stores all over the country and from Canada. I would expect the quality to be the standard for the company. Amazon does not have the leverage or order in the quantities that the BB stores do.

I ordered my Kohler Karbon faucet for my kitchen from a vendor on line and saved a bundle.

CHECK THE PART NUMBER. If it's exactly the same then it's the same product. If it varies by even one digit then it may be different and be of a different quality.
