Do you combine shipping for MULTIPLE ITEMS won. I will accept the return if miss something EVERY TIME. Winning bidder pays shipping. Just want everyone to know if something happens in shipping or we miss a listing you are 100% covered just will not allow buyer keep products for free when scammers can claim damaged.

Pretty good deal for buyers as this is NO RISK to you at all I am assuming ALL risk and stand behind my products. That is the global shipping hub. It is very sad that I have to even mention this but if you are buying something takes a bulb and see it works in my photos means the worked when listed. I only ship through global shipping.

Grass 7DAH Polygraph DC Driver Amplifier 7P8H Sphygmomanometer EKG-Pulse Pre Amp. Use the same mindset for batteries. If you are buying a used item it may have scratches scuffs. Will it be packed securely.

On that note. Sad I have to even mention this and not trying be difficult but lost a lot of hair because buyers arguing about 10 cent bulbs life batteries. Don't plan on batteries lasting the life of a product if I say it comes with.

If one burns out plan on replacing it yourself. I am human and can miss things. Unable to test, has cosmetic wear and could use a cleaning sold as is. I got you covered.

This is for your protection and ours. From here global shipping is in charge of the package. Please review all 12 photos to see condition. Just not fair.
