The only way to get authentic handbags is usually thru a liqudator.
There is a liquidator out there that has coach, D&B, Kate Spade, Betsy Johnson etc.
You will realistically never find Gucci, Fendi and Chanel at wholesale. They only deal with huge retailors who invest Millions in their inventory. Makes sense right? Why would they go thru the trouble of selling a few pieces to a small E-tail or boutique when they can make $$$$ with Saks, Neimuns etc who spend TONS of money.
STAY AWAY from anyone offering LV. It WILL be fake as will most of their other products. LV does not wholesale Ever!!
You can check out places like Handbagcrew.com, but I cannot vouch of their authenticity. Also every now and then Liquidation.com as some Prada etc.
Just keeping searching for liquidators and do your homework and check up on them to make sure they are legit. I know fo a liquidator, but they sell in huge lots, one per month generally, and the cost is about 45,000 USD.
*So even when you do find a legitimate liquidator, it is for those with $$$ to invest.
