@shotie23 --- Retail stores in Get to Work (including bakeries) sell items to customers. Items are priced by the owner Sims.
In Dine Out, your Sims run a restaurant, and customers come to eat. You select your menu, as well as outfits for the chef, the waiter and the host.
Although in both packs, Sims own public properties and gain perks by doing well, the game play is different. Perks are similar to, but different from, satisfaction points to purchase reward traits.
So, if you don't care about the new careers that Get to Work provides, then, both Dine Out and Get to Work have options to sell items, but in different ways, as I explained above.
Another point is that in both packs, retail store owners and restaurant owners may pursue careers and have a side store or restaurant --- Although, if you purchase Get to Work, your Sims could run a retail store on their time off, as well --- even if they have one of the three "active careers" --- you follow your Sim to work, and see the hospital, science lab or police station where they work.)
In Get to Work, The hospital, (your Sims can get sick) science lab and police station are all 50X50 lots. You can also get Mangolia Promminade which has 4 lots for your retail lots, including bakeries. You also get to go to the hidden world, Sixam, which is the alien's breathtakingly beautiful planet. If you're not a scientist, you can still go there by building a rocketship with a wormhole upgrade.

However, you need to place a satellite dish --- to encourage or prevent alien abductions. If you're not a scientist, then, get the satellite dish from debug (misc. electronics.)

Get to work has more buy/build mode individual items, as well as more clothing (although some of it is career-related (i.e. a doctor's lab coat and gloves.)
