eBay Beware Of Shipping Cost Game Playing

You're in Mexico so I don't think this applies, but Digikey will ship an order free in the US if you prepay. It's what I do when I don't need something in a rush.

Regarding Ebay, the sellers are pretty much up front on their shipping charges but you have to check the 'shipping' tab and make sure what you're getting yourself into. Some will send you a custom invoice if you ask them to combine shipping first before paying.

Once ordered a case of filters off ebay, they were delivered the next day from Amazon.

Hmmm...

I always shop around, sometimes eBay is cheaper, sometimes Amazon and sometimes another source. I also keep an eye on where it is being shipped from, if you want it in a reasonable time for a project and the eBay guy is shipping from China it might be a month.

and on ebay, if you buy multiples, request an updated price and often then you'll see the price for shipping not go up per unit.

And on amazon, if you do the next day shipping with prime, it's $xx per ITEM. So what do is order ONE with next day shipping. Then do another order with the rest I want with 2 day shipping. 9 times of of 10 they ALL arrive the next day and I only paid for one for next day shipping.

I recently needed some plastic trim clips for a car. They weight almost nothing. A dealer site had them for $2, shipping included. I figured I'd order 10 to reduce the per-unit shipping, but it was still $2 each. I ended up getting 15 clips off of ebay for half the total price the 10 would have been.
