We often use a background removal tool so that you get to see all aspects of the actual product. We try to sell products at a fair price and do not care of make money on shipping but do need to cover our expenses. If youre interested in one of our products but the shipping seems out of line, please contact us so we can review the ebay shipping calculator and perhaps come to an agreement. Additionally, we try to be the lowest priced for similar items so if you find we are not the lowest for an exact matched item reach out and make us an offer! Power cables shown in listing are often interchangeable so you may not get the exact power cable shown in the listing; however, it will be in working and good condition similar to what is shown in the listing. Similar to previous comment, I take my own pictures and in the vast majority of my listings (new items may be the exception) what you see is what you will receive, no more and no less. If theres ever a problem, please reach out so we can make a fair effort to resolve positively! We can only resolve what we know of.
