Searching for correct names, & websites, of 2 computer parts trade, & hobbyist, suppliers in Bangkok

Dear Fellow Thaivisa.com Members,

Looking for 2 "Computer & Electronic Parts Suppliers" recommended to me, & quite popular to Thai in the trade & Falang hobbyists, as offering good value, with respective names similar in sound to :

1_

L & M [ Website-Platform like Lazada.co.th ; But, NO pay on receiving Goods facility ]

&

2_

WCU & City [ Sounds something like that, I think only 8-) ]

or

CCU & City [ Sounds something like that, I think only 8-) ]

Owner / Manager ( Male ) operating from Condominium building in Bangkok, Thailand.

Welcomes customers physically calling to that address.

Apologies for having but sketchy leads to prompt ur recall ;

I was given them verbally ;

And, I had mind-block trying to memorise them.

Of course, I tried extensively on search engines prior & to no avail locate them.

Regards,

Our Man in the Tropics
