Set up discount email - to clean things up, set up an email specifically for collecting coupons and discounts without cluttering your personal email.
Avoid dynamic pricing traps - clear browsing history and logout of social media accounts to avoid being targeted with higher prices.
Contact customer service - many times by chatting with a customer service representative they will give you extra discounts to complete your purchase.
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.
Shop on the better day - the majority of stores roll out discounts and special deals on Wednesdays, Thursdays and Fridays. Avoid completing your purchase on Mondays.
