Why does the text "Priced From" appear before the prices on my website?
That text appears when a configurable product has associated simple products that have different prices. When Magento sees a range of prices for the associated simple products, it inserts that text to let the customer know that depending on which version of the configurable product you pick, there might be a price difference.
You can see in Magento, the first associated simple product on the Associated Products tab has a different price than all the other associated simple products. If this is intentional, as in a larger size, then leave it be. The text will remain on the site. If this should be the same price, simply update the price for that simple product, and the text will disappear with the next site re-index and cache clearing.
