Darn, I wrote a post then accidently deleted it.
The store is in acres of asphalt. Driving by, its hard to determine the best way to enter Arco to access the store. I would have to think most of their current customers are people specifically going to the store, and even more, people who go to a game or other event.
They could use some really good directional signs out on the major roadways and even in the parking lot, pointing the way to the store. Maybe light up signs that say "store open," as well. It might draw in some people who weren't specifically going to go to the Team Store, but see the signs and decide to stop in. Maybe a billboard visible from I-5 that has store hours and directs people to the exit(s) to take.
Fan packs would be nice if you get an overall discount for purchasing a pack of items.
I always like sales and discounts. This could be a percentage off a single item or a discount for multiple purchases of an item, like two t-shirts. If you were a family of four, and wanted to buy everybody a t-shirt, it would be nice if you could get a multiple item discount, such as one t-shirt for x-dollars, but two or more for x-dollars. It might be nice, too, if you were buying multiples for Christmas presents, too.
Maybe a really good discount coupon once a month. Printable from the internet or in the Bee or???? It could be used for internet purchases, but locals might actually come to the mortar and brick store with a coupon.
If I was out of town, I'd probably like free or cheap shipping.
