I'm just getting to the point of wanting to ship some peripheral boards, motherboards, etc... but I'm reading a lot of people will use the large flat rate boxes for shipping. I have truly never used one before and just realized it's $18 and some change to ship that box. And they're being a little generous with the word "large." If I'm paying nearly 20$ to ship, that's eating into the money I would be making per package since I'm not sending in product by the pallet. Is this honestly the best option for most people? I understand that drop off is ideal if you're close enough but I'm a good 3+ hours away from anything I've seen and I just can't afford the space to let it build up a whole bunch for a big trip. I'm just trying to send in a box full when I get enough for 20$ here and 30$ there sort of thing but shipping is going to make that feel really not worth my while. I'm holding off from sending anything till I'm sure if that's the best I can do. Any and all wisdom appreciated.
