Seller Feedback and Ratings

Always check the seller's feedback score and read reviews from previous customers. A seller with a high rating and positive feedback is generally more trustworthy.

Return Policy and Warranty

Before making a purchase, ensure that the seller has a solid return policy and warranty. In case the product does not meet expectations or is defective, a good return policy can save you frustration.
