Im rating only based on gundam/hobby supplies as I only ever come here for that. The price for gunpla is reasonable in my opinion if you take into consideration the currency rate of yen to CAD + shipping costs + store profit + taxes, maybe Im wrong on that aspect but It sure beats ordering online for me as I have to use the cheapest shipping method to not overpay for my gunpla fix as well as the wait time (couple weeks to a month) due to paying for cheapest method. I guess its all convenience if you want a gunpla kit asap, then animextreme's large selection of kits got you covered.
For hobby supplies, there really isnt much hobby stores within reasonable distance for me so coming here for the occasional flat coat spray or tamiya acrylics is really convenient. The selection for paints is rather small though.
