A little nervous with the USPS going forward

[Seven]

For those of you (and there were many) who commented on my recent situation involving the misdelievery USPS, The card I ordered never turning up, then being relisted by a completely new seller an entire state away from me, I wanted to thank you all for the helpful advice. As an update to the entire situation, I still haven't seen the card, I don't think I ever will which is unfortunate, so I'm in the process waiting to hear back from Ebay after filing a claim with them.

However this entire situation has made me lose all trust in the USPS. To the point where I'm kind of afraid to order anything of significant value ever again. Does anyone have any suggestions concerning this? Normally many things are listed on ebay using USPS for shipping. Additionally I've seen it used by board members here many times. Should I contact sellers on ebay of potential things I'm considering buying and ask them if they would ship them through UPS, where I would obviously pay for that of course?

I appreciate any and all opinions. Thank you again for all the help over the past week and a half.
