Three kinds of business sell it: a grocery chain with a standalone freezer chest, a welding or industrial gas supplier that treats it as a normal product line, and the odd independent ice-cream or party shop that keeps a block in the back. None of them ship it to you, and none of them are SMKlog, which is a separate errand covered below.
Dry ice sublimates whether it is in a box or on a shelf, so the trip to buy it belongs right before the trip to hand the box over.
Large chains including Walmart, Kroger-family stores, Safeway and Albertsons, and Publix keep dry ice at a good share of their locations, almost always in its own freezer chest near the front entrance or the customer service desk rather than mixed in with the bagged cubes. Stock is set store by store, and demand runs heavy around Halloween fog machines and summer coolers, so a phone call before driving over saves the trip.
Companies that sell bottled gas for welding and manufacturing, Airgas among them, sell dry ice as a routine retail line at branch locations nationwide, often under a house brand. These branches carry it every business day rather than seasonally, which makes them the dependable choice when the shipment has a fixed date and the grocery store gamble is not worth taking.
Any business that already handles hard-frozen product on a walk-in basis, an ice-cream parlor, a specialty butcher, a party or costume shop near Halloween, sometimes sells small blocks or pellets to walk-in customers even though it never advertises the fact. A short phone call establishes this faster than a search engine does.
Not the corner drugstore, not a hardware store, and not the mail. No parcel carrier will move loose dry ice to your door as a retail purchase, because it is a Class 9 hazardous material once it is in transit; buying it is always a local, in-person errand, one that has to happen close to when the box gets packed.
Dry ice loses somewhere around 5 to 10 pounds a day to sublimation even inside a well-insulated cooler, faster in a cheap one. That single fact decides the shopping trip: buy it the same day the box goes out, ideally within an hour or two of the carrier pickup, never the night before if it can be avoided.
Buying the dry ice gets your cooler cold. It does not get you a shipping label from SMKlog: our online checkout does not sell labels for dry ice, perishable, frozen or biological contents, a rule stated on our shipping restrictions page and enforced automatically by the quote engine. What each major carrier permits, and under what packaging and marking rules, is covered on our dry ice shipping rules page; the coolant math for a whole cold shipment, gel packs included, is on our cold food guide. A shipper who genuinely needs to move a dry-ice package works directly with a carrier's own dangerous goods desk, not a self-service checkout.
Large grocery chains, welding and industrial gas suppliers, and independent ice-cream or party-supply shops are the three reliable sources. Grocery stores usually keep it in a standalone freezer chest near the entrance or the customer service counter, separate from the regular ice bags.
Yes. Stock at a grocery store is store-by-store and often seasonal, heavier around Halloween and summer holidays and thin the rest of the year. A gas supplier is the more dependable pick when the shipment date is fixed.
That is the point of buying it locally rather than online. Dry ice sublimates at roughly 5 to 10 pounds a day even packed well, so it should go in the box within an hour or two of pickup, not the night before.
No. Our online checkout does not sell labels for dry ice, perishable, frozen or biological contents; the block is automatic and matches our shipping restrictions page. Buying the dry ice is a separate errand from buying the label, and the label errand ends at a carrier's own dangerous goods counter.
