The question asked, verbatim: best third party logistics providers for online stores

Brands named, in the order the engine gave

1. AMZ Prep mentioned
   One caveat up front: most "best 3PL" listicles are written by 3PLs that rank themselves #1 (ShipHype, AMZ Prep, Shipfusion, and Red Stag all do this in the results below), so treat rankings as leads, not verdicts.
2. Shipfusion mentioned
   One caveat up front: most "best 3PL" listicles are written by 3PLs that rank themselves #1 (ShipHype, AMZ Prep, Shipfusion, and Red Stag all do this in the results below), so treat rankings as leads, not verdicts.
3. ShipBob mentioned
   ShipBob - the default for most DTC brands.
4. ShipCalm mentioned
   (Fit Small Business (https://fitsmallbusiness.com/shipbob-vs-shipmonk/), ShipCalm (https://www.shipcalm.com/blog/best-3pls-for-shopify/))
5. Red Stag Fulfillment mentioned
   Red Stag Fulfillment - if anything you ship is over ~5 lbs, oversized, fragile, or high-value.
6. Amazon MCF mentioned
   Amazon MCF - only if Amazon is already your center of gravity.
7. Shopify mentioned
   One inventory pool serving Amazon + your Shopify store is genuinely convenient, but 2026 was a rough year: single-unit fees rose $0.35-0.41/unit (4-5x the FBA base increase), plus a 3.5% fuel surcharge from May and holiday peak surcharges of $0.35-1.00/unit.

The answer, as recorded

Here's who I'd actually name, roughly in the order I'd consider them. One caveat up front: most "best 3PL" listicles are written by 3PLs that rank themselves #1 (ShipHype, AMZ Prep, Shipfusion, and Red Stag all do this in the results below), so treat rankings as leads, not verdicts. **1. ShipBob - the default for most DTC brands.** Biggest network of the bunch (60+ warehouses), which is the whole point: split inventory across nodes and you get cheap 2-day ground to most of the US. Roughly $2.50-3.50/order for the first 4 picks, +$0.20-0.25 per extra item. Watch the fine print - they mark up shipping rates 15-30% and add a 3% card surcharge, so the headline pick rate understates true cost. ([Fit Small Business](https://fitsmallbusiness.com/shipbob-vs-shipmonk/), [Fulfill.com](https://www.fulfill.com/shipbob-vs-shipmonk)) **2. ShipMonk - better economics if you're mid-size, and the one for subscription boxes.** ~$2.50 first item + $0.50 per additional, dropping toward $1.80 at volume, no setup fee, free inbound receiving, and pallet storage around $25/mo vs ShipBob's $40. Fewer facilities (12+, all self-operated, plus Canada/Mexico/UK/Czech), so less zone-skipping benefit. No monthly order minimums, which matters if your volume is lumpy. ([Fit Small Business](https://fitsmallbusiness.com/shipbob-vs-shipmonk/), [ShipCalm](https://www.shipcalm.com/blog/best-3pls-for-shopify/)) **3. Red Stag Fulfillment - if anything you ship is over ~5 lbs, oversized, fragile, or high-value.** The generalist 3PLs quietly punish bulky SKUs. Red Stag is built for them and backs it with real SLAs: $50 paid to *you* per fulfillment error, zero shrinkage allowance, 5pm same-day cutoff. ~$1.80-2.25 first pick, ~$0.75/cu ft storage. Only two warehouses (Salt Lake City, Sweetwater TN) and a practical floor around 200 orders/month. ([WarehousingCosts](https://warehousingcosts.com/guides/red-stag-pricing-review), [Red Stag](https://redstagfulfillment.com/big-heavy-bulky-3pl-fulfillment/)) **4. Amazon MCF - only if Amazon is already your center of gravity.** One inventory pool serving Amazon + your Shopify store is genuinely convenient, but 2026 was a rough year: single-unit fees rose $0.35-0.41/unit (4-5x the FBA base increase), plus a 3.5% fuel surcharge from May and holiday peak surcharges of $0.35-1.00/unit. The 2026 Preferred Pricing program claws back up to 15% at high volume. Unbranded boxes and Amazon controlling your customer data are the real costs. ([Feedvisor](https://feedvisor.com/university/multi-channel-fulfillment/), [GeekSeller](https://www.geekseller.com/blog/amazon-announces-multi-channel-fulfillment-2026-preferred-pricing/)) **5. eFulfillment Service - if you're doing 10-300 orders/month.** Genuinely no minimums, no setup fees, no long-term contract. Most of the names above will either reject you or price you badly at that scale. ([ShipCalm](https://www.shipcalm.com/blog/best-3pls-for-small-businesses/)) **6. Shipfusion - worth a quote if you need cold chain, lot tracking, or Canada.** 1M sq ft across IL, PA, NV, and Toronto, with dedicated account managers. Narrower network, but the lot-tracking and temperature-controlled capability rules out most competitors for supplements, food, and cosmetics. ([Shipfusion](https://www.shipfusion.com/fulfillment/locations)) **7. DCL Logistics - complex products and retail channel.** The one to call if you need EDI compliance for retail POs, kitting, or serialized electronics rather than straight DTC picking. ([Red Stag](https://redstagfulfillment.com/best-3pl-companies/)) Two things that matter more than the shortlist: nobody publishes real rates, so get quotes from three on *your* actual SKU dimensions and order profile - pick fees are a minority of your bill, and shipping markup plus storage is where the money goes. And ask each one what happens at December peak, since surcharges and receiving delays are where 3PL relationships usually break.
