I was shopping around for a very specific LCD monitor (Samsung 172T), and buying mainly on price. I found Provantage after several websearches, and despite extremely volatile pricing (the price literally varied around $100 on a $600 item over the course of a week), they were consistantly one of the lowest prices.  
 
First, the bad news. Their online tracking frankly sucks in comparison to other resellers (I use NewEgg as my yardstick, so I do possibly have unreasonably high expectations). This is mainly due to their method of shipping from regional centers; they had the package listed as shipped for 3 days before it was actually shipped though.  
That's it, that's the bad news. Their pricing was superb, the order process pain-free (they even call to verify orders), the screen arrived undamaged and in perfect working order, and exactly when they eventually said.  
 
They're not in danger of knocking NewEgg off my first-check place, but they're definitely on the list.

We purchased a Vantage Pro Davis Weather station and after doing lots of shopping around, we found Provantage by far had the best prices. We were very impressed with the service from Provantage, they were prompt in answering our questions. They shipped when they said they would and didn't gouge us with outragous S/H charges. We will do business with this company again. Thank you Provantage

I ordered an NEC FE791SB monitor from Provantage, on November 23, 2002. It arrived in good shape, but I noticed that some of the packing was held together with masking tape. Although the box apparently was factory sealed, I became supicious that it was a returned or refurbed item. I called Provantage to report it, and was told that Provantage does not deal in refurbs. While on the phone with the customer service rep, I examined the box further, and found that it had indeed been opened, not from the top, but from the bottom. I told the customer service rep about it, and she said that if I wanted to return it, they would send a replacement.  
 
From all appearances it was a new monitor, so I decided to try it out first, before returning it. That's when I became a believer. This has to be the best monitor I have ever used. It is flat fantastic! I'll never buy a cheap monitor again. I decided that I had a winner, so why bother to to return it. It's now 2 1/2 months later, and I'm still a believer. Buy the best monitor you can afford, you won't be sorry.

Bought a couple of IBM Ultrabay HDD adapters.  
 
Quick delivery, good price, no problems. Great eBay'er ... oops, not eBay, just a good merchant.

I ordered a set of speakers from them yesterday, the 6th. I received them the 7th. I paid for regular shipping, and I didn't evne get a chance to try and track it. It just came the next day. I was really surprised. I have ordered from them before and they have given similar quality services. Everytime I check prie comparisons, they have some of the cheapest prices out there. I would DEFINITELY order from them again.

Great on the sale, LOUSY on the return! I would not do business with these people again due to difficulty of returning defective product, lack of response to e-mails, etc.

Nice selection - Viewing real-time inventory is an added bonus. Shipping prices are a little high but product prices make up for it.

Best internet retailer I've dealt with online hands down. Their customer service reps will go out of their way to accomodate you.

Incredibly fast delivery and great prices and selection. One of the smoothest internet buying experiences I've ever had!

Very good service. Accurate inventory. Good software prices. Sometimes you can find a great price on a hardware item as well. One of the routine "stops" when I shop the Web.

I ordered a NEC fe1250+ 21inch monitor.Provantage has the best price and reseller rating on this monitor, fast shipping,this monitor is wonderful and works perfect the only thing is, it has a really bright screen but with some adjustments I love this monitor and I have had the viewsonic p815 21 inch and the sony g420s 19 inch and this monitor is a lot better as far as guality.Good job Provantage, good price and good product.I will order again.

Ordered an Antec PLUS1080AMG case - excellent price and shipped very quickly. Excellent vendor.

Great price and fast shipping.

Always fast service and reasonable prices.

They sold me a Compaq wireless network adapter that was DOA. No tech support at Provantage. After many hours on phone with Compaq tech support they determined DOA card. Provantage refused an exchange or refund. If you buy anything from these people and it's DOA, you've lost your money. Provantage's return policy is "NO RETURNS!". Look for another reseller.
