* For e-Commerce shipping it is easy to simply slap a shipping label on a single item or sample shipment, than to repackage or double package a retail, "store shelf ready," presentation quality, product container. In other words, OEM packaging saves everyone a buck or two. e-Commerce and mail order companies prefer plain, space efficient packaging and not just for reduced shipping costs. Everyone, supplier, shipper and customer, benefits from the reduced cost and reduced mi s-shipment and "shrinkage" (glossy, high color packaging attract thieves, just like it attracts customers in a retail store). This is also a much "greener" solution that many of our-customers will appreciate.

* Input Power: If your product is aimed at the international as well as domestic markets, especially for mobile operation, use a power supply "brick" that will work from 100 to 240 VAC, 50 to 60 Hertz and is of the "two blade" variety (isolated, no ground prong). This helps during "brown outs" and power surges and is easy to use overseas without inverters. These "universal" or "international" power supplies can work just about anywhere in the "first and second world" and most of the "third world". This will save a significant number of support phone calls and requests for unprofitable, optional supplies. Don't reinvent the wheel here ... it will increase inventory costs, tech support and sales grief later.

* Output Power: If possible, make the output voltage from the power supply brick 11 to 14 VDC, and less than 500 milliamps. This will match the power from 12 VDC, auto, truck and solar power adapters. This makes your gadget "mobile". You may have add DC regulation on your circuit board to accommodate this, although many USB and FireWire 1394 chip sets have this on board regulation.
