Best time to buy seeds from I49 if you're not waiting for 4/20?

H HolidayShopper 3 weeks ago ✓ Best Answer

Black Friday/Cyber Monday usually has pretty decent sales. Or just keep an eye on their 'Promotions' page.

I ImpulseBuyer 3 weeks ago

Ah, totally forgot about Black Friday. Thanks!

D DealSpotter 3 weeks ago

Promotions page is key.

E EmailHunter 3 weeks ago

Any random 'flash sale' emails they send out. Sometimes they're good.

S SpamChecker 3 weeks ago

Gotta check those spam folders.

Anyone know if I49 does student discounts?

S SavvyScholar 1 month ago ✓ Best Answer

Nah, but check for universal discount codes. Sometimes UNIDAYS or similar have stuff that works.

C CollegeCultivator 1 month ago

Never thought of that.

S StudentStoner 1 month ago

Oh, that's a good idea! Thanks!

N NoobNugs 1 month ago

Haven't seen anything official mentioned on their site for students.

S StudentStoner 1 month ago

Bummer.

Does I49 have a loyalty program or cashback for repeat buyers?

R RepeatBuyer 3 weeks ago ✓ Best Answer

Not a formal points system like some places, but I get better offers on their newsletter after a few orders.

L LoyaltyLover 3 weeks ago

Good to know! Thanks.

F FrequentFarmer 3 weeks ago

Same experience.

What's the usual discount for first-time buyers on I49?

F FirstTimerFan 1 month ago ✓ Best Answer

I think I got 10% off my first order. It popped up automatically.

Q QuickHarvest 1 month ago

Mine was 15%. Maybe depends on order size?

C CuriousCultivator 1 month ago

Following.

T TextyTrader 1 month ago

Mine was tied to signing up for their texts. Got a code that way.

N NewGrower23 1 month ago

Interesting, I'll try that.
