Shopping in Blue Island

Biking strengthens, tones, burns off calories, and relieves stress. It also reduces your carbon footprint by conserving precious fuels that are better spent building new bicycle factories (whose products will lead to even more fuel conservation, and so on). And biking costs you precisely $0 per gallon, saving you buckets of cash. Although today's Groupon for the Marin Kentfield FS is not $0, it's close enough—and pretty much a steal, given the quality of Marin bikes. The Kentfield FS is especially perfect for commuters, but will also serve you well on a rigorous workout sesh or a leisurely Sunday ride. A lightweight aluminum model, it only weighs 27.5 pounds, so even those who are flabby of bicep can lift it with minimal effort or strain. While its 700 x 35 tires translate into smoother rides, its powerful brakes will help you stop safely. Finally, its Shimano shifters and derailleurs will provide the control and flexibility you seek as you shift between its 21 gears.

The Denim Lounge's jean-centered staff aids customers in selecting an ideal cut, color, and style of premium denim pant to complement their body type. Fellas sport fashionably casual leg wear, such as the Big Star slim-fit jean ($50), and ladies partner their favorite cashmere blouse or chainmail under-armor with Hudson Signature boot-cut denim ($106). The clean double-stitching of DL1961 midrise ankle skinny jeans bestows legs with chic allure ($158), and Red Engine Jewel FireBrand jeans brandish dark colors that complement nightlife outfits ($167). For a complete ensemble, customers can take 20% off a second item, handy for matching a new pair of pants with a trendy top, snug sweater, or leopard-print blouse to intimidate purse-snatching zebras.

Get caffeinated for a cause with today’s side deal: $10 gets you a two-pound bag of Ugandan Bugisu whole-bean, family-farmed coffee from Crop to Cup and one free drip or espresso coffee every day for the month of October at @Spot Café. The bag of coffee is a $24 value alone, and with your daily complimentary cup of iced coffee, flavored coffee, or espresso, the value of today's deal can be tens of dollars more.

Love means having someone who will split your cable bill and co-sign on loans. Express your strictly utilitarian approval of that special someone with today's Groupon to Grow Flower Shop. For $40, you'll get $80 toward an artful flower arrangement and delivery. Grow delivers throughout the Chicagoland area, and local delivery begins at $12. If you want to hand-deliver your profession of flora, you can pick up your arrangement at Grow's shop in NBC Tower. To get your flowers for Valentine's Day, place your order by February 5.

Star Struck is the official provider of authentic Blackhawks and Bulls apparel, and carries tons of tees, caps, and more for all Chicago sports teams. Stay warm with a Blackhawks tassel knit hat ($15), or put your Groupon toward a Bulls playbook pullover hoodie by Adidas ($45). Pass yourself off as number one with a Jay Cutler women's jersey ($65), go vintage with a faded Blackhawks zip hoodie ($65), or layer for the Chicago cold with either a Blackhawks or Bulls three-in-one T-shirt combo pack ($30). Sports apparel also makes a great gift for all your expecting friends, whose soon-to-be babies would be naked if not for the Cubs onesies ($16) you so graciously provided.

Upon arrival, you'll be greeted with a bevy of showroom items to peruse. There are plenty of options that fall within the cost of your Groupon, such as a chrome Galaxy table lamp ($125), Tikal mirrors in cherry or black ($75–$125), a white Lima vase ($45), or Lawrence leather bookshelves ($125). There are also cozy couches, chairs, and more waiting to be adopted. The merchandise is always changing, but you can check out a few sample items here. If there's nothing on the floor that floats your boat, thumb through a large collection of manufacturer books to find that perfect piece. Someone will be there to guide you along the way while giving professional input, such as the storeowner, Kim Tepper.
