Quick Sourcing Tips

  • - Leave a buffer for repricing and unexpected prep costs.
  • - Avoid products with razor-thin margin even if ROI looks acceptable.
  • - Validate competition and seller count before buying deeper quantity.
  • - Re-check costs when using coupons because they can expire.
  • - Track your real fees by category; fee assumptions vary by size and weight.
Rule of thumb: prioritize products with profit above $5 and ROI above 30%, then confirm demand and competition in Keepa.
