Packets won on convenience and on the idea of hygiene, and for a lot of groceries that is a fair trade. For spices it is a worse deal than it looks, for four specific reasons.
Short answer: Loose spice lets you see, smell and test before you pay, buy the quantity you will actually finish, and get it fresher. A packet gives you a seal and a date - and the date is a packing date, not a freshness one.

You can test loose spice. You cannot test a packet.
Most of the useful home tests for spice quality need the spice in your hand.
Peppercorns in water: real pepper sinks, papaya seeds float. Cloves in water: a good one sinks or floats bud-up, a spent one lies on its side. A cardamom pod squeezed between finger and thumb should feel full. A cinnamon stick should tell you in one look whether it is Ceylon or cassia.
None of this is possible through a sealed pouch, and powder makes all of it impossible regardless of packaging. The entire toolkit for not being sold old or adulterated spice requires buying it whole and loose.

The date on a packet is not what you think
A packet carries a packing date and a best-before. What neither tells you is how long the spice sat in a warehouse before it was packed, or how long the packet sat under a shop light afterwards.
A spice that was packed six months ago, warehoused for four before that, and has been sitting on a warm shelf since, is a year old and reads as perfectly in-date.
Loose spice from a shop that turns over its stock is usually fresher, and you can tell by smelling it, which is the only test that actually matters.

Buying the quantity you will finish
This is the underrated one. Whole spices keep well - a year or two - but only while they are whole and only while the jar is full. Powder is finished in two months.
A hundred-gram packet of elaichi is a lot of elaichi for a household, and the last third of it will be noticeably worse than the first. Fifty grams, bought twice, is better spice for the same money.
Buying loose means buying twenty grams of javitri, or six star anise, or a hundred grams of the pepper you use constantly and thirty of the one you use twice a year. The packet cannot do that, and the waste it causes is invisible because it happens slowly.
How to buy loose well
Smell everything before it is weighed. This is normal and expected. A shop that minds is telling you something.
Ask when it came in. A spice shop knows. "Last week" and "a few months" are both honest answers and both useful.
Buy whole, never ground. Loose ground spice loses the one advantage of buying loose and gains the disadvantage of having no seal.
Take your own container or transfer it the same day. A paper packet is for carrying home, not for storing. Everything should be in an airtight jar within the hour.
Buy little and often. It is the whole point. A shop two minutes away that will deliver the same day makes it practical in a way it is not in a city.

Questions people ask
Is loose masala less hygienic than packets?
Not in a shop that keeps stock covered and uses clean scoops. What you gain is the ability to see and smell what you are buying, which is the larger risk with spices.
Is loose spice cheaper?
Usually, per kilo, because there is no brand premium or packaging cost. The bigger saving is not buying more than you will use.
How much spice should I buy at a time?
Whole spices: what you will use in a year. Ground: what you will use in two months. For most households that is 50 to 100 g of the common ones and much less of the rare ones.
Can I check spice quality in the shop?
Yes, and you should. Pepper and cloves in water, a squeeze test on cardamom, a look at the end of a cinnamon stick, and smelling everything.
Does the date on a packet mean it is fresh?
It means when it was packed. It says nothing about how long the spice sat before packing or how warm the shelf was afterwards.
Do you deliver loose spices in Salumbar?
Yes. Order before 5 PM and it reaches the same evening, weighed to whatever quantity you ask for, free over ₹200.
