Avoid dynamic pricing traps - clear browsing history and logout of social media accounts to avoid being targeted with higher prices.
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.
Free Shipping - always look for free shipping coupon codes or for the minimum free shipping amounts to score this discount.
Set up discount email - to clean things up, set up an email specifically for collecting coupons and discounts without cluttering your personal email.
Use multiple email addresses - sign up for stores email lists using a couple different email accounts. Stores will offer single use coupon codes, combine these single use coupon codes from multiple email accounts to maximize savings.
