Browser Extensions for Faster Research
Price research is the most time-consuming part of reselling.
These extensions cut that time in half.
Keepa adds Amazon price history charts directly on product pages, so you see if a current deal is actually good or just temporarily inflated.
CamelCamelCamel does the same with email alerts for price drops.
Rakuten gives cashback on many supplier sites, which your spreadsheet should track as a cost reduction.
Honey auto-applies coupon codes at checkout, sometimes saving 5-10% on bulk orders.
Revolut or Wise browser extensions show real-time exchange rates with minimal markup, helping you calculate true costs for international orders.
Add an Extensions Used column to your spreadsheet so you remember which tools applied to each order.
