Here are some strategies for dealing with supplier price fluctuations in drop shipping 

Fixed dollar markup: Add a specific dollar amount to the product's price at your supplier.

Fixed percentage markup: Set your product's retail price at a certain percentage of your purchase price.

 Free plus shipping strategy: Sell a product for $0.00 and only charge the customer for shipping costs.

Cost-based pricing: Determine a selling price based on your expenses like marketing costs, COGS, hosting fees, and app costs.

Bundle pricing: Offer a product bundle: customers can buy your product and a different matching product and get a discount for both.
