Barbell

I've been looking at some barbells with weights on the internet to gauge the cost and stuff. I found some pretty cheap barbell weight plates but the hole was 28MM which doesn't fit with most bars. I mean, i can buy a 28MM bar but if that store stops selling the weights, i am fucked. So i definitely want to go for a 30MM bar with weights. It seems that i will have to dish out at least 200$ to get the minimum. The worst thing is that i want to mainly use the barbell for hip thrusts (also for squats) but with hip thrusts you can progress with weight real fast, which means that i have to invest in more weights. I will have to check how much money i have on my bank account (i haven't checked in a while) to see if i should make this purchase, otherwise i will have to wait at least 1 or 2 months, which is fine, i guess. 

I found one website that has a sale right now where the weights and barbell are really cheap but the problem is that on a surface level a 20kg weight for 40 bucks doesnt seem that bad, until you realize that you need two of them. I also found a "beginner" set up for 80 bucks that gives you the barbell with 30kg worth of weights and that seems to be the cheapest deal right now. I don't think i have to go with the most expensive or best gear since i am a light weight and i can barely lift 10 kg anyways lol. But i will still look around more to see what bang i can get for my buck.
