For his birthday, I would like to buy my dad a something for his bike that would allow him to carry a few groceries. He has expressed interest in using his bike to run errands around town, but he is not interested in buying a utility bike.
Currently he has been using a backpack to buy small items like produce, milk and bread. I'm hoping to get him something that can carry 10 - 15 lbs.
Given his carbon fiber seatpost, my options are limited:
I can find a rack that works with a CF seatpost (i.e. Topeak RX (http://www.amazon.com/Topeak-Beam-Carbon-Fiber-Bicycle/dp/B000ZKFXK2) ), but reading reviews around here it sounds like it's still not safe and they're really expensive.
Another idea is to use a large saddlebag. Like the Carradice Barely Bag (http://www.carradice.co.uk/index.php?page_id=product&product_id=43). It seems like people like these bags, but I'd like to get a perspective from the utility crowd.
I'd like to get rid of his carbon post and replace it with an aluminum post, but I'm not sure he'd agree.
Any other ideas? Anyone ever use Carradice Bags for groceries? Is it any safer to use a heavy saddle bag on a CF seatpost?

I picked up a trailer for $25 from a yard sale. 100 lbs limit.
You can also find some on craigslist now and then.
Got this free. Owner had it his trash pick up at the curb.
The wheels pop off and the trailer folds up to be placed inside closet or up against a wall for storage.

What about a rack that attaches to the brake bridge instead of the seatpost? The he could use panniers. Such a rack wouldn't be quickly removable, though.

Lot's of options here and all good choices too!
My suggestion is to mount a frame mounted rack. There are many frame mounted racks to choose from so check around.

The Axiom streamliner (http://www.axiomgear.com/products/gear/racks/streamliner-series/streamliner-road-dlx/) rack attaches to the brake bridge and is pretty nice looking. I've seen a few people with them and they look pretty good on a road bike. Narrow width up top, however, so they are just for panniers and won't hold a rack trunk.

KlickFix makes a seatpost adapter and a basket of nylon,
steel mesh, and natural materials, that has a support ring that snaps
onto that adapter.. you can load it, at the check out, then put it back on the bike..
Some shops credit a nickel for not using their carry bags..
How far is he riding, hills/speed required to deal with traffic, and how much (in volume, weight) in groceries? I run "Honey, pick up X at store on way home from work" some days I bike to/from work. For just a few miles and small quantity/size of items, the backpack I use when I ride my road bike is fine. I can carry a full sack or 2 of groceries on my commuter because it has a rear rack. Short of using a trailer (10 Wheel's excellent examples), a basic lightweight aluminum rack mounted using either a brake bridge adapter or a seatpost clamp tapped to take rack brackets - they exist - and p-clips for the seat stays, and a pannier easily carries a full bag of groceries, and the load imbalance is not that big a deal for a short grocery run. Even a simple rack is going to be reasonably light & stronger than a seatpost rack. I don't think rack trunks, Carradice bags, etc. would provide sufficient additional space to justify the cost.
A handlebar bag might work for small loads, but it will depend on how mounting and how much it affects bike handling. My limited road bike sample size (2) suggests they can become very twitchy unless they've been designed to take a front load. My guess is your dad's bike is not one of them.

There's tons of options available, but if he's using a carbon fiber seatpost he's not going to like the weight of any of the other options. A backpack is probably the best choice until the volume of freight exceeds its capacity and he is forced to reconsider his position.

There's the Xootr Crossrack and Crossrack Bag, although I don't know if it's wise or otherwise to use with a carbon post.

One of these is suitable for small grocery runs; http://www.peterwhitecycles.com/carradice.asp
Another option would be something like these;
I use both of the above options (Carradice and arkel with tailrider) on my Specialized Roubouix CF. Mostly I use them when doing long self supported rides; however, I have also used them on my morning rides to have some place to put a few odds and ends when I stop at the store on my way home.

I use a kiddie trailer. It's easier to load than a bike-attached bag. I just toss the stuff in. It's also easier to pedal, since keeping the bike upright doesn't require increased effort. Capacity is insanely large. I've towed well over 100 pounds. I get trailers used on craigslist.

So, he's got a CF seat post....what about the rest of the bike? Carrying static weight on a light road bike is hard on the frame and wheels, so converting a kiddie trailer for errands might be the best way. Carradice bags are great. look classic and can carry a surprising volume but large heavy items like a gallon of milk becomes iffy. If you carry the weight high like that it effects handling. If it were I, I'd buy the old man a Carridice Bag....I hope my boys are listening ;)
