There is no simple answer to this question as it depends on a number of factors. In general, Yakima products are typically cheaper than Thule products. However, there are exceptions to this rule and it is possible to find Thule products that are less expensive than Yakima products. It really depends on what you're looking for and where you shop. Some stores may sell both brands at the same price, while others may have discounts or sales that make one brand cheaper than the other.
When comparing prices, it's important to keep in mind that Yakima and Thule offer different levels of quality and features. Yakima tends to be more budget-friendly, while Thule is known for its premium quality and higher prices. If you're looking for the absolute cheapest option, then Yakima is probably your best bet. But if you're willing to spend a bit more for better quality, then Thule is worth considering.
