Set up discount email - to clean things up, set up an email specifically for collecting coupons and discounts without cluttering your personal email.
Enter multiple coupon codes - combine multiple coupon codes at checkout to score the biggest savings. Also referred to as stackable coupons; combine a sitewide coupon with a free shipping code.
Request price drop refund - some companies will give you a refund for the difference in price if the product you purchased drops in price.
Free Shipping - always look for free shipping coupon codes or for the minimum free shipping amounts to score this discount.
Avoid dynamic pricing traps - clear browsing history and logout of social media accounts to avoid being targeted with higher prices.
