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.
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.
Use reward programs - check out such products as Swagbucks and Shopkick, these companies will give you special discounts and gifts for filling out surveys and shopping around.
Keep patient shopping cart - by not completing your purchase quickly, merchants will reach out to you and offer better pricing or more coupons to encourage you to complete the purchase.
