Sears offers the X-Cargo XL 15-Cubic Foot Car Top Carrier, model no. 90040, for $159.99. Coupon code "SEARS5OFF50" drops it to $154.99. Opt for in-store pickup to dodge the $90 shipping charge. That's $35 off list and the lowest price we could find, although we saw it for $40 less last fall. It holds up to 100 lbs. and fits most vehicles.
