I do ship/rec. for a living and I'll give ya some insider info, here goes nothing......
1. UPS has published rates and tiered rates. For example, you and me pay published rates at the UPS store, SummitRacing pays a tiered rate cause of the shear volume that they do.
2. My work charges our "tiered rates" to the customer and a 45 cent surcharge per package to help offset the cost of tape, boxes, packaging materials so on. So if a package costs 12.45 at our rate and the published rate is 14.28 the customer has saved money because we charge what our tiered rate is plus the 45 cent surcharge.
3. The fuel surcharges that are added weekly by UPS are automatically set into our rates and they fluctuate on a weekly basis.
4. We used to do almost 90% of our shipping with UPS, not that much anymore, let me explain.......there is a service called hundred weight and when you hit 200 lbs for a shipment you get a price drop, but by shipping freight (truck) I needed to be around the 500 lb range to be comprable to UPS rates...not so anymore. If I send 200lbs. by truck it is cheaper and also gets there in 1 piece vs. Ups. Example, I sold some parts to a guy in CO., UPS charge was gonna be 70, plus two oversize pkgs., additional handling and the quote was 126.00, by truck it was 92 bucks and he gets it all in 1 box on a pallet and saved over 30 bucks.
4. Trust me when I tell you UPS is feeling the effects of people moving over to truck freight instead of using them.
5. One last thing, ALL SHIPMENTS ARE INSURED AUTOMATICALLY FOR 100 BUCKS BY UPS AND THIS IS FACTORED INTO THE COST OF THE PACKAGE!!!!!! So if someone offers insurance for an extra fee and is using UPS tell to F**K themselves and look elsewhere for your part.
Class dissmissed, lol!!
