If you land at JKIA from Asian countries,the KRA guys will definitely insist on checking ur bags. Like Pablo & Wendz have said,remove the(price and other) tags and pack the (clothes) in ur bag such that your dirty shoes and used socks will be on top.
From European countries,just walk confidently towards those KRA guys,and appear like you want to surrender ur luggage to them for inspection....they just ask u what's in it and let you walk away....
if its electronics,better use Salihia Cargo and go collect ur stuff at Eastleigh. @ 260 per KG
