Shipping

Canada Post has begun the process of safely ramping up and stabilizing operations across the country. With a large, integrated network of processing plants, depots and post offices, stabilizing operations will take time and the company asks Canadians for their patience.

Canadians should expect delivery delays through the remainder of 2024 and into January 2025.

Canpar has issued a delay in service notification due to increased shipment volumes and inclement weather in some areas.

Petland ships orders Monday through Friday (excluding statutory holidays). We use Canada Post, Purolator & Canpar for delivery. "Free Shipping" will usually be sent through Canpar Ground service. Canpar Ground & Purolator Ground services do not have guaranteed delivery times and the shipping times will only be estimates.

Orders made online after at 11 AM CST on Fridays will ship the following business week. When considering delivery times after an order is placed, please allow 1-3 business days to process your order. Courier delivery times do not include the day the order has been picked up from our warehouse.

Orders that include "special order" items will not be shipped until the "special order" item arrives in our warehouse.

Please provide a street address if you choose "Free Shipping", Canpar or Purolator as your shipping method.

If you have a PO Box, Rural Range Road, Township Road or Site land location address, you must choose Canada Post as your shipping method.
If your address is an apartment or condo, please include the buzzer number.

Both Canpar and Purolator shipments will require a signature upon delivery unless you have requested the shipment to be left at your front door with "no signature required". ** If you do not make this request and are not home to receive your order, an attempted delivery notice will be left at your front door. The notice will indicate the depot where you can pick up your shipment.

**Please note that neither Petland nor the delivery service is liable for any lost or stolen packages if you have requested the shipment to be left at your front door.

Undeliverable packages:

Occasionally, we will have a package returned to us because it was undeliverable. When this occurs, we will issue a full refund for the price of the product plus taxes. Shipping charges are non-refundable. If your order had "Free Shipping" the shipping charges incurred by Petland for your order will be deducted from the total product refund amount.

We can receive packages as undeliverable for the following reasons:

Missing house number, unit number or buzzer number

Can't even handle 1 gallon of water.

I bought this little heater to put in a 3 gallon hospital tank. (My current heaters were too big for such a little tank.) It's in an already warm room (23C/73F) and I only needed it to raise the temp a few degrees as per instructions on the medication. The light comes on, suggesting that it's working, but the heater itself only gets marginally warmer and after 24 hours the water is still room temperature. I removed 2 gallons of water from the tank because the instructions said it's only good for .5 to 1.5 gallons and I figured I must have been over working it, but it can't even keep 1 gallon warm. Complete waste of $30.

Good heater, mostly

I got this heater for my 3.5 gallon betta tank, and I must admit, it overheats it sometimes. It never actually turns off as far as I can tell, so it definitely doesn't keep it at the desirable 26 C. I just blow a fan on his tank since it's the summer right now and that keeps it just right. In the winter, I'm sure it will do it's job perfectly, but be warned: this WILL cook your fish if left unattended. It would probably work better for a 5 gallon, honestly, but for my 3.5 or anything less, it overheats it.

Works Wonderful!

Have it in my 5.5 gal tank. Keeps the water temp at 76 deg. I used to have in my 1 gal tank and even in that small space it still kept a consistent temperature.

Best mini heater around!

They advertise it for only 1.5 gallons but it was able to efficiently heat my 5 gallon very well.
No problem, one of the most reliable mini heaters. Would even compare this to my fluval e heater, but that is for my turtle and heats 100 gallons.
All in all its great. Cant get better for the price

Awesome!

this is my 3rd "betta" heater .... betta smetta..... this is a great heater for your 2.5 -10 gallon TANKS! these great little heaters are thin and sleek AND totally sit either under the gravel or on the bottom of the tank. HELLO
