Just to let you know, I am incredibly biased when it comes to Costco. I've been shopping there since it was known as Price Club back in the 80s. Now that I am all grown up, I have a membership of my own. I usually shop here twice a month. That said, not all stores are created equally. The Arundel Mills store is only a few years old, and has always been very clean and well-organized.
A quick overview of several departments:
Tires--I agree with Nate on this one. The Tire Center is great... Your tires will be installed while you shop, and there's often a coupon or special to be had. I've purchased three sets of tires from here, and have been very happy with the product and installation. One caveat: the line can be long on some days, so if you can't get there first thing (they open at 10), give a call first to make sure that you won't have to wait too long. I would recommend avoiding the Tire Center entirely on the weekends. Way too busy! Two other notes: 1) Costco only fills tires with nitrogen. Yes, you can "top off" a nitrogen-filled tire with regular air, but it's not ideal. The techs will top off your tires any time, and since I'm there with some frequency, that's not an issue for me. 2) The tire center also provides a free tire safety check any time you'd like one. The techs will inspect the tires while you shop.
Photos--Place your order online, and pictures are often ready the same day. One-hour processing is also available. You can order photo cards (holiday, birth announcements, etc.) and enlargements as well. The customer service reps are friendly and helpful.
Jewelry--Bling in all price ranges. Not bad but not great either.
Electronics--Decent selection, competitive prices.
Office Supplies--I am such a nerd for this kind of thing, so the 30-pack of Sharpies is appealing to me. A fun aisle to peruse. Includes kids' crafts, picture frames, and school supplies.
Bakery--features in-house items such as cakes, cookies, breads, pies, and muffins. I usually try to bypass this section entirely, but I must tell you that I buy a pumpkin and pecan pie from here every Thanksgiving.
Produce--mostly hits with a few misses. I think that the new stuff still arrives on Tuesdays, so shop on Wednesday morning for the best/freshest selection. Would like to see more organics.
Clothing--decent selection for babies, kids, and adults. Prices are competitive but not always the lowest in town.
Media--good selection of books, DVDs, and CDs (does anyone buy these anymore?).
Grocery--from staples to spices to specialty items, I've found lots of great products. I buy organic milk for Chickadee here (3 half-gallons for under $10 / stock limited to whole milk & 1%). Additionally, the Costco store brand, Kirkland, is very reliable.
Another thing to look for is gift card discounts. Two $50 gift cards for SpaFinder, Starbucks, and McCormick & Schmick's (among others) sell for $80. Last month, there was an instant rebate on Godiva gift cards, and a $50 card (normally $40), cost only $20. Needless to say, our moms received chocolate for Mother's Day!
I've never purchased anything from the optical department or pharmacy. There is a gas station here as well (12 pumps), and the price is usually .10 cheaper than what you'll find along Arundel Mills Blvd.
There is a changing table in the women's room. Your little kiddos may like it when the employee who checks the receipt draws a happy face on it. The employees seem generally friendly toward Chickadee--I do appreciate that. Another kid favorite is the samples (usually available from 11-6). Yum!
A reviewer for the Beltsville location complained about having to buy four boxes of "macoroni and cheese [sic]" at a time. Um, yeah, that's the point of shopping at a warehouse club! If you have kids, and you have some storage space, go for it. read more
