My friend finally found a cheaper and proper shipping solutions after weeks of finding.
I will start sending out invoices to those had yet to received, and will refund the difference to those already paid for this, it should be a few dollar cheaper to around $8 cheaper for EURO countries like Germany, Sweden & etc. (FROM >$28 to around $20).
We target to all ship all orders out by the weekend, sorry for the waiting, but I personally feel this is more acceptable price for shipping fees.
