you are absolutely right! I've done that with fabric and lots of other bargains! I was shopping for my brothers se 400 on walmart, ebay, amazon etc. The machine was about $369. Walmart marked it down for $309; I played around hoping they would mark down even lower; the next day I purchased the machine from walmart for $309 (free shipping to store); other websites dropped their prices to about $320. The day after my purchase walmart increased the price to $399 and that is what the machine has been and still is today! I am a witness; buy it when you see it because you may not see it again or if you do chances are it will not be the same price!
