Wanted to know what's the preferred carrier for shipping detectors nowadays? I use to use priority mail for about $20, went to send a detector out recently and now they wanted almost $40. I ended up sending it parcel select for $17 they said it would take 6 to 8 days, been 12 days still not delivered. I'm getting a bad feeling about this, never had any problems with priority shipping. Is FedEx or UPS better and/or cheaper?
