EE broadband pricing - new customer

I'm looking at taking out EE broadband 1 Gbps service (I have openreach fibre on 500/70 already with giganet).

Until about a week ago the summer offer was 44.99 (I think, could be 45.99). I actually went to order on the last day, but it was about 2245 and the website went down - not to come back until later where the prices had gone up (annoying!). I bailed

Currently the price is 47.99, though a few months ago it was 57.99

Whilst we can't predict the future, any thoughts on how variable EE's pricing is here. Do we think we may see it lower? I'd love to see a graph of recent prices to help answer that!

I'm not desperate to switch, so black friday may be another option - what were the BB offers there like?

EE also does cashback over time. I'm not a big fan as it's not guaranteed. Quidco.topcashback are showing none currently, but my employee portal (smart spending) is showing £90. At best that's a bonus not to be replied on.

I have EE perks, but think this only applies to mobile.

I am an EE mobile customer, but the app fails (Sorry, a technical problem) on all devices/connections I've tried when trying to link through to broadband sales. Calling up so far has elicited just the standard price as per website.

Any input appreciated - thanks!

Finally, you may ask why EE? It started with giganet annoying me by removing static v4/v6 and adding up to 4s latency. I concluded I can do without static, but latency and connectivity really matter. Too many stories of challenges with some isps. I feel the BT network will be solid, albeit within the offering's limitations (no flexibility & annoying marketing/recontracting!)
