I launched my product a month ago and since then I've had one paying customer which felt great but my product is extremely cheap as a major selling point compared to competitors.
I don't have the biggest twitter network but I've used that to tweet about it and also posted it on a few subreddits but I don't want to spam.
Does anyone have any tips for it?
There are a lot of acquisition channels you can use (see the link on my profile for some ideas). You can post on Reddit again in a non-spammy way. Just use a different angle for the post (things I've learned while doing X, a question-based post and so on.)
