There are a few pieces of advice that may be smart to follow if you want to avoid being scammed. First you should never agree to a lower price once you have already determined a price with the buyer. Second you should never take more money than you were quoted for by promising to make up the difference later. Lastly if you are offered payment in a non cash form like a voucher or a coupon you should not follow through with the sale. If any of these things happen to you then you should walk away. Instead you should work with a trustworthy company like us.
