Direct Answer
BAC Water Depot ships bacteriostatic water free on orders of $250 or more, up to 100 vials; smaller orders pay a flat $15.99 for USPS Priority Mail and cases over 100 vials ship for $34.99. Every order placed before 2:00 PM CT Monday–Friday ships the same business day from Dallas, TX.
Which bacteriostatic water orders ship free?
Free shipping is set by the order subtotal: $250 or more ships free, up to 100 vials. With 10 mL vials at $9.99 each, $74.99 per 10-pack and $174.99 per 25-pack, the common ways to cross the line are four 10-packs ($299.96, 40 vials) or two 25-packs ($349.98, 50 vials). Anything from $250 up to 100 vials ships free by USPS Priority Mail.
Watch the near-miss: one 25-pack plus one 10-pack comes to $249.98 — two cents short, so it would pay the $15.99 standard rate. Adding a single $9.99 vial takes the order to $259.97, which ships free: you receive 36 vials and pay $6.00 less than the 35-vial order with shipping.
What does shipping cost on orders under $250?
Orders under $250 pay a flat $15.99 for USPS Priority Mail, whatever the size. That flat rate matters most on small orders: a single vial delivered costs $25.98, a 10-pack delivered costs $90.98 ($9.10 per vial) and a 25-pack delivered costs $190.98 ($7.64 per vial).
If you will use the vials, the delivered cost per vial falls fastest by moving up a pack size rather than ordering single vials repeatedly: every separate order under $250 pays its own $15.99.
How do Express and case shipping fit with free shipping?
Express (1–2 business days) is always a paid upgrade and replaces standard shipping: USPS Priority Mail Express at $45.99 or $1.50 per vial, whichever is higher — $45.99 covers up to 30 vials, 50 vials cost $75.00 and 100 vials cost $150.00. An order of $250 or more can ship free by Priority Mail, or by Express at the Express rate.
Orders over 100 vials leave the free-shipping program and ship as a case for a flat $34.99, at bulk pricing of $6.99 per vial from 50 vials, $6.74 from 150 and $6.49 from 500. For bulk quantities and quotes, the bulk page covers ordering and case pricing.

Frequently Asked Questions
How do I qualify for free shipping on bacteriostatic water?
Free standard shipping applies automatically to orders of $250 or more, up to 100 vials — for example four 10-packs ($299.96) or two 25-packs ($349.98). Orders under $250 ship USPS Priority Mail for a flat $15.99, and case orders over 100 vials ship for $34.99. Orders placed before 2:00 PM CT Monday–Friday leave Dallas, TX the same business day.
Does a single vial of bacteriostatic water ship free?
No. A single 10 mL vial is $9.99 and ships USPS Priority Mail for a flat $15.99, so free shipping starts at orders of $250 or more. If you use more than one vial, a 10-pack ($74.99, $7.49 per vial) or a 25-pack ($174.99, $6.99 per vial) lowers the delivered cost per vial.
Is Express shipping free on orders over $250?
No. Express (1–2 business days) is a paid upgrade on every order: USPS Priority Mail Express at $45.99 or $1.50 per vial, whichever is higher — $45.99 for up to 30 vials and $75.00 for 50 vials. Choosing Express replaces standard shipping at checkout, and orders placed before 2:00 PM CT Monday–Friday ship the same business day.
How long does free shipping take?
Free orders ship exactly like paid standard orders: USPS Priority Mail, which USPS estimates at 1–3 business days for most US addresses. Orders placed before 2:00 PM CT Monday–Friday ship from Dallas, TX the same business day, so free shipping is not a slower service tier.
Why does free shipping stop at 100 vials?
Orders over 100 vials ship as a case for a flat $34.99 instead of free standard shipping. At bulk pricing the case fee is small per vial: about 35 cents per vial at 101 vials and 23 cents per vial at 150 vials, where bulk pricing is $6.74 per vial.
Does BAC Water Depot ship free outside the United States?
No. BAC Water Depot ships research-use-only bacteriostatic water to US addresses only, so free shipping applies to US orders of $250 or more, up to 100 vials. There is no international shipping option.
