Walmart -vs- Target

This morning we took a trip to the local Walmart as a friend told me about a deal on soup that she found the day before. I went to see for myself & lo and behold they had Campbell's Cream of Mushroom and Cream of Chicken soup (10 3/4-oz cans) marked for .58 cents a can. If you ever buy it, you know that normally it costs anywhere from $1.00 on up, so this was a bargain. I stockpiled on both varieties. However I found a twist on this that I think is worth noting.
The price label that Walmart had posted on the shelf under the soup cans had a small black star on the right hand corner of it. I didn't think much of it until I looked at the other stickers around it and none of them had this on there. Ok, so I then looked at other stickers on different products and only certain ones had it. I scouted out for an employee to dig deeper into this. What I was told was that this was an internal note to the employees. In essence it told them that this was a promo item. So I questioned the employee as to how long this "promo" would be offered. No specific date was given, but they did state that this will run through Thanksgiving and possibly into the New Year holiday. After that it may stay this price and run through the year, but it was not a guarantee so it may possibly stop and go back to the regular price (which in our store is $1.00) after the holiday season.

I got a sales flier in the mail yesterday from Target that listed a few of their Thanksgiving items on sale as of Sunday 11-15-09.
The other offer that peeked my interest was for Stove Top brand stuffing, Betty Crocker potatoes and Heinz jar gravy for .79 cents. This is a good price, however I noticed at Walmart they are offering the gravy in turkey only for .75 cents a jar. Target's ad just says gravy...no specific flavor so I can only assume (but suggest you check it at the store to make certain) that any variety would be at this sale price.
