First of all yes, that is i correct information about the big item then the accessory.
As far as getting your scores up, I would in the beginning suggest a contest to get the awareness out there, not just electronics but store wide. Talk it up at huddles, as well as one on one to each other. The contests that i had, had the most success with is keeping a log or a bingo card of the amount someone gets. At the end of the week who ever has the most gets a free lunch at target cafe or a free drink and snack if its a starbucks. Then at the end of the month have the reward be a little bit more substanical, such as a dvd or cd of there choice. After the culture has been changed and people are asking I would not have the contest. I am a firm believer in contests once in awhile is great, but a contest every week or month is just rewarding people for doing their job. If you have any questions feel free to ask, I feel like I have so much Target knowledge in my head, its going to explode at times, lol.
