Sound familiar?
Fifteen tabs. Three carts. Still not sure which is the best deal.
SourceSmart does the math on every factor — so you don't have to guess.
What Does a Purchase Really Cost?
The sticker price is only the beginning. Shipping fees, estimated taxes, your Prime membership, the gas to drive to the store, your time — these are real costs that change which option is actually cheapest. SourceSmart adds them all up so you know before you buy.
Compare More Than the Advertised Price

From Our Members
Real savings. Real decisions.
"I almost paid $94 for something I found for $71 after SourceSmart factored in shipping and my Prime membership. That's a real $23 saved on one search."
"This does in 10 seconds what used to take me 20 minutes and three browser tabs. I don't shop without it anymore."
"Recommended it to my sister after she bought from the 'cheapest' site and paid $15 in shipping anyway. The price really isn't the cost."

Built from a Real Purchasing Decision
We run a spice blending operation. When we needed 120 empty spice bottles, we compared two suppliers. Supplier A had free Prime shipping. Supplier B was $24.50 to ship.
Supplier A looked like the easy choice — until we asked the right question: what does Prime actually cost us per order?
We use Prime roughly 30 times a year. That makes each order's share of our $139 membership about $4.63. Add that back in — and suddenly Supplier B won by almost $11.
The price was not the cost. SourceSmart™ was born.
Frequently Asked Questions
What is True Cost™ analysis?
True Cost™ is the complete cost of a purchase — not just the sticker price, but every factor that actually affects what you spend. That includes shipping and handling, estimated taxes, your pro-rated membership costs (Prime, Costco, Sam's Club), gas and travel time if you're buying locally, available coupons or rewards, and more. SourceSmart adds all of these together so you can compare what you'll actually pay across retailers.
Is SourceSmart free to use?
Yes — basic price comparison across retailers is free with no account required. Founding Members unlock the full True Cost™ calculator with all 12 cost modules, saved searches, and a personalized savings dashboard. Current intro offer: $0.99 (regular price $9.99/mo).
How does SourceSmart handle Amazon Prime and other memberships?
The membership cost calculator divides your annual membership fee by the number of times you use it each year to calculate a per-order cost. That amount is added to any purchase that requires the membership — so free Prime shipping is no longer free if you're using Prime infrequently.
Does SourceSmart compare prices including shipping and tax?
Yes. Every comparison includes shipping cost breakdowns and estimated sales tax based on your location. Hidden handling fees — which some retailers add separately from the listed shipping rate — are also flagged when detected.
Is SourceSmart a price comparison calculator or a shopping tool?
Both. SourceSmart is a price comparison calculator that goes further than advertised prices. It calculates the total delivered cost of each option so you can make an informed decision — not just see who has the lowest sticker price.
