Coffee at Costco, PX Mart or momo: where is it cheaper per 100 g? (2026)
Updated · by the Today's Coffee Taiwan team
Short answer: for whole beans, the typical price per 100 g is NT$79 at Costco, NT$94 at PX Mart and NT$150 on momo (our momo list has more specialty coffee, which costs more); the lowest we found is Barista Blend 2 lb (momo, NT$55). For drip bags the lowest is NT$10 per bag (Costco), and for instant sticks NT$4 per cup (PX Mart). Costco sells big bags (0.9–1.4 kg) and needs a membership; PX Mart sells small bags close to home; momo has the widest choice and deals that change every few days.

Careful with the "typical" price on momo: our momo list includes many specialty and single-origin coffees, while Costco and PX Mart mostly sell everyday blends. To compare the same thing, look at the lowest prices or at the same brand below.

Which shop fits you?
- Costco (好市多): big bags of 0.9–1.4 kg at a low price per 100 g, including Costco's own brand Kirkland. You need a membership. A 1.13 kg bag makes about 90 cups at 12 g a cup.
- PX Mart (全聯): close to home, small bags of 225–454 g, and offers like "any 2 for" that lower the price if you buy two.
- momo: the widest choice, with specialty and single-origin coffees, and deals that change every few days. We check its prices every 3 days on Deals.
A big bag only saves money if you finish it while it still tastes good. Keep it closed, away from heat and sun, or split it into smaller airtight bags.
Common questions
Which Costco coffee beans should I buy?
We don't rank them. The table above shows the price per 100 g of each; Kirkland is Costco's own brand and is usually the lowest per 100 g. For taste, check the roast: medium for black coffee, dark for milk.
Does PX Mart have buy-one-get-one coffee?
Sometimes. Offers change often, so the "Offer" column shows only what we saw on the date above. Check the PX Mart app or the shop before you go.
Are Costco online and in-store prices the same?
Not always. The Costco prices here are from its website and include delivery; prices in the warehouse can be different.
Do you earn money from Costco or PX Mart?
No. The Costco and PX Mart links are normal links, not affiliate links. We only earn a commission on momo and partner-roaster links.
How we make these guides: momo prices are checked every 3 days. Costco prices come from costco.com.tw and PX Mart prices from its 小時達 delivery site, which shows in-store prices; we check those by hand once a month and show the date. "Typical" is the middle price of each group. We earn a commission when you buy through our momo and partner-roaster links; it never changes your price. We review this page every 3 months.
