    A++ eBay seller. This is the third time I’ve been back to this seller and he knocks it out of the park every time with the best of service. Shipping has always been extremely prompt and everything has always been packaged extremely well. Communication is always been top-notch. Pricing is also attractive. If you see something you like from this seller, don’t hesitate because he always comes through in the best of ways. I’m sure I’ll be back to buy more from him before too long.
