Why Don't We Show The Price?
MAP ("Minimum Advertised Price")
Some manufacturers require internet retailers to display a price at or above manufacturers established MAP ("Minimum Advertised Price").
Since our price for this product is lower than MAP, the manufacturer does not allow us to display our lowest price until you place the product in the shopping cart. This allows us to continue offering our lowest prices while staying consistent with product manufacturers policy.</p> <p class="text-justify">This process does not require you to purchase the product - it can be easily removed from shopping cart if needed.

PRICE MATCH
GUARANTEE
PumpProducts.com is dedicated to always offering the best value to our customers. We will match the price, at the time of purchase, on a Price Match Guarantee product if you find the same item at a lower price at a Designated Major Online Retailer or at a local retail competitor's store.
Here's how:
- If you find a qualifying lower price online, call 800-429-0800 and direct a customer service agent to the website with the lower price, or when visiting a PumpProducts.com store, one of our employees will assist you.
- On qualifying products, PumpProducts.com will then verify the current price to complete the price match.
PRICE MATCH CONDITIONS
- The manufacturer and model number must be identical.
- PumpProducts.com will match prices of direct competitors. Our direct competitors include any retailer who sells products in both retail stores and online under the same name. PumpProducts.com will also gladly match price on any items sold by Amazon.com (but not by a third party on Amazon.com). For further clarification, market place sellers on websites not their own are not considered direct competitors.
- Membership clubs are not considered direct competitors.
- When matching a competitor, PumpProducts.com will follow any limitations and exclusions set by the competitor.
- The item must be first quality. PumpProducts.com does not match prices on seconds or refurbished items.
- PumpProducts.com does not match prices on clearance items, closeouts, liquidation sales or pricing errors.
- Competitor product must be available and in-stock at time of price match request. Price match does not apply to items promoted as “limited time,” “limited quantity,” “while supplies last” or any similar language.
- PumpProducts.com reserves the right to limit quantities on a price match to one per customer.
- A customer can choose between the PumpProducts.com price with a coupon/offer OR the competitor price but may not use a coupon/offer with the competitor price unless the competitor would accept it.
-
A manufacturer’s coupon may be used in combination with a price match.
Note: Any coupon that is issued from a retailer or brand that also has retail stores is considered a competitor coupon, not a manufacturer coupon. - Price Match guarantee is valid on price of item only, not on shipping and/or handling charges.
