We are a retailer of accessories, collectibles and giftware based in Canada.
Some ways we have tried are coupon promos, social media and print ads. What other tactics should we try?
TV and Radio are not an option due to a small budget. We typically don't spend more than $500

Did you try radio and TV (if you can afford it)? Not really sure on your budget...
