Should I switch from David?

I have bought 6 watches from David, but his prices have hiked up which was the reason I bought watches from him, I was trying to get a Clean Pepsi V3 for my bf but David’s price is nearly 400 Yuan more expensive to Lin Feng’s, and my experience with David has been amazing he even repaired a watch for me after I got it, and gave me a discount for the shipping cost on my next order, but since David accepted PayPal I initially paid insurance and via PayPal for the peace of mind, but Lin Feng uses WeChat which looks a bit sketchy and only accepts wise so I wanted to know if I am contacting the right guy. So just like I did with David I send money and wait for QC?? Also does Lin Feng sell watches with the boxes?? David charges 200-400 Yuan for the boxes usually.
