About the Seller : RFPlus

I'm Jon, a lifelong hobbyist, professional engineer and now occasional seller on Ebay, having sent over 10,000 items around the world over the past 17 years. I am not a business/company despite Ebay's classification to the contrary, though I do have a lot of parts and gear which should go to a good home.

All parts for sale are my private property, in stock in Cornwall, Southwest UK, and ready to post to the world via Royal Mail, or if larger/heavier via your arrangement/collection. I post via UK First Class post: my P&P charge is at cost but I'm happy to combine multiple items in a package for that one charge. You may need to use the Ebay Cart (and request a total if Ebay miscalculates).

If there's a problem with anything, I can send a replacement order, refund your money or do whatever it takes to make you happy. I hope my feedback gives you the confidence that I'm good to deal with. Any questions, please ask!

Thank you for reading ...   Jon @ RFPlus
