In the (paper) Yellow Pages for your area.
You may have to go to the public library to find this.
Why so old fashioned?
I already mentioned they are local. You can visit and see what you are buying for resale.
Look for liquidators, jobbers, manufacturers, factory outlets attached to factories, wholesalers and importers.
They will want payment immediately, but most will take a credit card which gives you an automatic 30 days to pay.
Later on you may get 30 day billing, but don't expect this on your first visit. All too often that has been the last visit too.
Sell what you know: know what you sell.
Ask the salespeople you buy from for your profession about purchasing.
If you are a plumber, selling plumbing parts. If you are a hairdresser, sell beauty products.
Ask about end of lines, returns, deadstock that B&M businesses can't use.
The Yellow Pages take about six months from contract to publishing. This means the companies you are dealing with have been in business for over six months.
That may not be true of the flashy website that catches your eye online.
Also, wholesalers probably get a tax break when they sell for resale. So if you are not being asked for your business license or tax number, you are probably paying full retail.
You may not be required to have one, but a real wholesaler will at least ask.
Also.
Dropshipping is not a good idea. Seriously.
