Amazon offers the Gillette Simply Venus Refillable 3-Blade Razor with 4 Cartridges Refills for $5.49. Clip the $3 off coupon on the product page to cut the price to $2.49. Plus, Prime members receive free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, shipping costs $5.48.) That's $3 under what you'd pay in-store locally. (For further comparison, we saw it for a buck less last July with orders of $25 or more.) It includes a pivoting head and a moisture strip.
Update: Note that this item is temporarily out of stock, but can still be ordered at this price for delivery when available.
