Hello

I need an professional email to approach multiple salons to buy my cosmetic bags.

I have a small business of cosmetic bags I want to inform them in the email that they buy the bag and they add their profit I don’t want they the other way around that i will display the bag and once customer buys them they send the money to me .

the bag that i have i sell it for 250 dhs which is around 68.07
what do you recommend as a business wise since i well sell around 50 to 100 piece should I lower the price since its a bulk order or should i tell them same price and they add the profit to it
